DPSSim is standalone program written in Java that tries to simulate Arms and Fury warrior DPS rotations.

You can choose rotation/priority list to use (or even create one), length of fight, stats and talents of your character, available buffs and run simulation to get info about DPS, damage breakdowns, uptimes and other statistics (ie. average swing time, average time between executes etc.).

This tool has been created mainly to allow easy testing of different rotations/priority lists for given gear/buffs/talents, but due to many configurable options I believe it can be used also for other things.

Please post bug reports, new features propositions here. Unfortunately my free time is very limited at the moment so I cannot guarantee when or if at all any of them will be implemented.

I've only tried the Arms portion of it and overall it seemed well concieved and very useful. However, there are some basic parts that are unnecessarily complicated, mostly involving stat inputs. because the stats you pull off your character screen are already modified by talents, one must figure out half the stats by adding them up from gear, also making the weapon damage input as a min/may damage rather than average. The other thing I noticed was that there is no option for beserking as a weapon enchant, nor is there an allowance for trinket procs and or stacking buff trinkets such as Fury of the Five Flights.

This aside, its a very solid basis for a program and its 1 of only 3 Arms DPS simulators available, that is if you even count maxdps.com. The other is Doc's PVE simulator which is wildly inaccurate in my experience.

Nice program, but I have some problems:

- What's the average dmg of my weapon? DPS or ((min+max) div 2) ?
- Everytime I start a new simulation, the program shows a new DPS number. Is that intended?
- After the simulation, I found that I had 109% GCD usage. wtf? 8-)

Stat input: in this way one can easily check influence of talent choices from within simulator. Unfortunately for now I don't see solution that would give both this and easier filling for your character - good thing is that you need to do it only once and then only change on gear upgrades. Maybe in the future there will be Armory import option - for now it looks like quite a big time investment for me for not so much needed thing.

Weapon damage input: well, for me it is easier to just calculate average and enter one number. It is also consistent with layout of other input fields and additionally takes less space.

Enchants/trinkets: added to things to do in future. Have in mind however that for all proc effects I need clear info about PPM/mechanic/internal cooldowns before I'm able to implement it.

Thanks for your opinion :-).

Ad 1. (min+max) div 2
Ad 2. That's because it is simulation, not spreadsheet, which means it is influenced by RNG the same way as real fight - sometimes you got lucky on SD/ToB procs, sometimes not, which of course has effect on your final DPS. One way to limit fluctuations is to average all RNG things by setting fight length to higher values. Generally 300000s+ gives good enough approximation for me, ten times that if I want really small differences.
Ad 3. Interesting. Could you provide rotation you used and damage breakdown from Results tab? Possibly I count maximal available GCDs as 1 less than it should be (ie. in fight of 3s length available GCDs number is 3 not 3/1.5=2).

Is it possible to integrate the code into Rawr?

I don't know much about Rawr! but I think it would be quite hard thing to do - different concepts of implementing the same thing, probably also different programming languages.

However if someone would like to try, I can send sources of DPSSim.

DPSSim.jar updated

- bug with incorrect GCD usage percentage fixed (too small available number of GCDs + Heroic Strikes were counted as GCD usage)
- 3% increased critical damage meta gem added (available as static buff)

I thought about your statement that it's not a spreadsheet but a simulation. The effect is that I run several tests (~20) and try to figure out what's the average DPS ... then I change a stat and do the same again. Isn't there any option to include the average DPS straight away?

With simulation you almost never get one final value for DPS. However as you said averaging results of several simulations is a way to get some approximation. And I have something like that in mind (that is automatically running several simulations in a row) when I think about implementing SEP calculation in the future. So, yes, I think such option will be available, for now we must do it manually.

Great Program!

Will it be able - in future - to import Stats and Skills from Blizzards Armory?

It will only be possible if some other person than me will do importing module, as I don't have time right now.

Update:
- sets bonuses added (Set tab in main window)

Update:

- patch 3.1 build 9704 (many changes, check other topics on these forums for details); ArP rating changes not updated, also stacking of ArP for now is implemented as multiplicative
- Siegebreaker set added (no internal cooldown and 150 haste rating assumed - to be checked)
- enchants update (Berserking, Executioner)

does this mean, that the tool now uses hasted-weapon-speed (and not the base-weaponspeed) for procchance calculation?
i have very low uptimes(in the simulation), even with dual berserking. Simulation says 30-40%. on live server i have 50-75%+ with dualberserking, depending on my luck .


all in all i like this simulation tool very much! great job!

Yes, it uses hasted weapon speed for on hit proc chance calculation. I assumed 1ppm - maybe it is higher?

It's 1 ppm, but it uses base weapon speed.

Update:

- build 9722 (TfB 9s, IBS 15% strength)
- Berserking enchant will use base weapon speed for proc chance calculations now

Not certain, but likely all enchants

just out of curiousity: did you use any of my code for the custom priority list part?

No, I created it from the scratch, with aims/ideas I talked to you about (list/combo box of selectable abilities and conditions).

The view (combo box etc.) does not affect the model/internal implementation of the feature nvm though, as long as it is working correctly as your implementation seems to be.

edit: I'm getting only 430 'real' average damage on a 3.6 2hand offhand with DW-spec whereas the same 3.6 mh with the same 600 avg damage is at 1038 'real' average damage. if the offhand deals 62.5% te damage of the main hand, one of the numbers is wrong. is this a bug or is there something I'm missing?

Yes, I know it is ugly :-), everything packed in one huge class :-/. Would be nice to have 24h of free time each day to make everything perfect :-P, and this feature I wanted to have as fast as possible.
