I don't want to steer the discussion offtrack by turning this into a feature suggestion for a particular addon (when more appropriate venues may exist), but I would like to second the ability to only display the Swiftmend indicator if the target's health is at a certain level.

I like to keep my Grid fairly minimal and having the SM indicator display on every single raid member (with a HoT) is more of a distraction for me than anything else. For the time being I've modified your add-on to basically include GridSwiftmend's health threshold option. I'm not going to release this without either author's permission, but it is fairly trivial to do for anyone else interested.

If a target is low, you will see it from his healthbar. No indicator needed.
If a target is swiftmendable, an indicator would spam down the grid during a raid.
Grid goes not know if swiftmend is on or off cooldown by itself.

Criteria 1: Target is below set HP treshold: (i.e. 30%)
Criteria 2: Target has someones hot (swiftmendable)
Criteria 3: Your swiftmend is currently off cooldown.

If ALL of the above is true, an indicator called "LowHPTargetSwiftmendable" would trigger, which you could assign to a frame of your choice in grid. Either as text in center text, like "SWIFTMEND", or as a colored indicator which you could slap in a corner.
Since you can't set a frame in grid to require 2 indicators to fire, (like grids built-in low health + some other indicator related to swiftmend and it's cooldown), you would need a seperate addon to handle this trigger.

I believe this is what they are asking for.
edit: And I would like one as well!

This is exactly what the addon I posted does. Only time it's distracting on Grid is if Swiftmend is off cooldown after Precious/Stinky's decimate.

Hey Hamlet,

I've been trying to configure OpenRDX on my own, using your backup file as a base/starting point, but I can't figure out how to load your backup in OpenRDX.

Do I need to edit the .lua file? If it's overly complicated, no worries; I'll play around with it some more.

My particular thought process, and something I'm going to try applying to the rest of my setup, is this:

1) The less indicators* you need to look at and aggregate mentally before performing an action the better.
2) An indicator should not have "ignore me" scenarios AND "react immediately" scenarios unless the 2 can be differentiated by a clear visual display (such as color change).

*Note: Indicators does not mean a grid indicator it mean a visual indicator of any sort such as a cooldown monitor.

This is the issue with the 2 swiftmend addons recommended. One has "ignore me states" when swiftmend is on cooldown which cannot be made visually different from its "react quickly" state. The other requires mental aggregation of both the indicator and the health frame which also produces "ignore me" states when the health is above a certain threshhold. Now having the indicators display during the ignore states isn't necessarily bad, you can plan around them, however I do think its better if the indicator looks different when you shouldn't ignore it, so that you don't ignore it.

OK I'll edit GridCooldownSwiftmend in version 1.2 to add a new color to indicate that life is low and that Swiftmend can be launched

I think you're talking about this one?

If so, I don't see an "ignore me state". The pink number is my Rejuv timer and the bottom left box is my Rejuv indicator. SM only shows when it's off cooldown, a member has Rejuv or Regrowth, and they are below a health threshold. This is what I've said since my first post on the subject. Not sure where the disconnect is.

I completely agree with your post/philosophy otherwise. Also, I'm not trying to defend this addon. I don't care if people like it. Just setting facts straight.

I use borders for most important debuffs: Penetrating Cold, Mark of the Fallen Champion, etc. That leaves room in the center icon for less-deadly-unless-combined things like Boiling Blood and Acid-Drenched Mandibles. However, lately I have been feeling center icons are more distracting than helpful. The smaller DoT debuffs could be also be put in your Rejuv indicator's corner, with a lower priority, since that's mainly all we'll throw on them.

I also use borders for key effects, and save center icon for friendly cooldown buffs (Cloak, Iceblock, Shield Wall, Last Stand, etc). When there are multiple effects in a single fight that amplify each other--such as Sara's Fervor and Sara's Blessing--I'll promote one to a different slot so that I can see both. Typically I use the magic/disease indicator slots if the fight doesn't require those slots. On fights where knowing about simultaneous effects isn't that important or the effects can't overlap--such as BQL's important debuffs: Swarming Shadows, Blood Mirror, Pact of the Darkfallen, and Vampire/Frenzy/Mind-control states-- I'll just set up a reasonable priority and put them all on borders.

One thing I have been running into lately is that Grid has been hogging CPU like crazy. At last count, I have 22 custom buffs and 77 custom debuffs, and I'm also running a gaggle of grid-enhancing addons: StatusHots, SideIndicators, SideText, CornerText, RaidIcons. I've tried to strip out unnecessary stuff, but in 25-man especially the addon has been dog-slow. A performance measuring addon, KLHPerformanceMonitor, indicated that I am using upwards of 20% of my frame time in Grid. In comparison, my second-hoggiest addon, PowerAuras, takes less than 2%...

Try using GridStatusRaidDebuff. Each raid debuff is customizable and each instance set only loads on demand/zoning.

@Evillek - what boss mod is that?
