Hi guys !
I’ve made some calculations for a few days about Monk Brewmaster (one with the Power Strikes talent and a 2H weapon), to know the impact of each rating on the damage reduction we have against the melee attacks of a boss.
I wrote a program that considers we use Guard, the Black Oxe Statue (which implies calculating the dps of the Brewmaster – I’ve done it in the same way as the dps of the Windwalker, which is explained in the corresponding thread), Elusive Brew (I also take Tiger Strikes into account to calculate the proc rate), even Swift Reflexes… in fact the program includes everything except Zen Sphere since it is heavily modified nowadays, and Gift of the Ox, since I couldn’t get any information about its proc rate.
I consider we use Keg Smash every 8 seconds, Expel Harm every 15 sec (and I consider it doesn’t do any overheal, nor do Guard and the Black Ox Statue). There is still some energy per second left even with zero haste/hit/exp, I spend this energy on Jab.
I use Blackout Kick every 6 seconds to keep Shuffle up, and Guard every 30 sec. The remaining Chi is spent on Purifying Brew. But there is remaining Chi only above certain values of haste/hit/exp, since a missed Keg Smash consumes energy but gives no Chi, and a missed Jab consumes 8 energy. I did check that at 0 haste/hit/exp, using Keg Smash is an increased generation of Chi per second compared to a situation in which we would use Jab only. I consider that 80% of the downtime is spent on using a free Tiger Palm.
The results concerning Stamina only represent the AP increase via Vengeance (and I use the real formula stam->AP, not the wrong one in the tooltip), which causes an increase in dps (and therefore in the speed at which the Black Ox Statue will proc), and in the healing of Guard and Expel Harm.
The parameters are as follows (the name of some variables might not correspond to their description : they are in French ^^) :
- attack speed of the boss (time between two attacks)
- boss dps on the tank
- armour rating
- dodge rating
- parry rating
- weapon dps
- weapon speed (actually the calculation proves that it doesn’t interfere at all with tanking efficiency ; it simply doesn’t appear in the final fomula, because the damage of Monk abilities are not calculated in the same fashion as other melee classes, which means a Windwalker can chose any 2H weapon, regardless of speed)
- haste rating
- hit rating
- expertise rating
- agility
- crit rating
- mastery rating
- whether or not we have the crit buff (1 if we do, 0 if we don’t)
- whether or not we have the AP buff (1 if we do, 0 if we don’t)
- whether or not we have the Mastery buff (1 if we do, 0 if we don’t)
The damage reduction is :
As you can see, we can’t see a thing. I use partial derivative (if that’s what it’s called in English) to calculate the impact of each stat. For a Brewmaster with an equipment like that of my Monk on the beta, and for a boss hitting the tank every 2 seconds for an average of 100k dps :
Agi > Exp > hit > haste > parry > dodge > crit > stam > mastery
We notice that haste is like… waooh. This is probably due to the fact that it significantly increases both the number of Purifying Brew (since it increases the Chi generation) and the procs of Elusive Brew. And it increases dps, which increases the rate at which the Black Ox Statue is activated.
On the contrary, Mastery seems to be a very, very poor stat (fortunately, it will be buffed for next patch). The probable explanation is that we already have a base Stagger of 50% (30% stance of the Ox + 20% Shuffle) and Mastery doesn’t increase Stagger a lot. In addition, the staggered damage is one that is already reduced by other damage reductions.
I also made a little program that helps comparing the efficiency of our sources of survival. Note that the detailed numbers are not representative of the actual damage reduction, given the interaction between these reductions (you’ll notice that adding them won’t give a result of 57k overall) ; they are only here to give us an idea about how powerful is a survival technique. But the overall damage reduction is correct, and in this example, the Brewmaster does ignore an average of 57k damage per second :
I hope this will be useful, and that I haven’t made too many mistakes in the text (I haven’t written anything in English for a while).
