Is your feature request related to a problem? Please describe.
in the past i tend to run into a problem where a weakaura is not requied for melees since the mechanic avoids them and therefore a load condition to exclude melees would be neat.

Describe the solution you'd like
the only way I know to make this possible is GetSpecializationInfo.
Basically making a list of speccs and assigning them to AmMelee or AmRanged.
This would require updating whenever a new class is added but should be rare.

i could make a full list, including the api etc if you intend to implement this.

Describe alternatives you've considered
baking it into the trigger, doesn't avoid the WA from wasting resources though

Are encounters consistent regarding targeting ranged vs. melee? That is, the same specializations are 'melee' for all mechanics that target melee and the same specializations are 'ranged' for all mechanics that target ranged in all encounters?

I was under the impression that this has been somewhat inconsistent in the past.

afaik melees are only targeted by ranged-mechanics if there's a lack of ranges e.g when most ranged players died. there sure has been times where melees aren't targeted regardless

that said, I doubt that most melees would suddenly care about a mechanic because most ranged died.

a better implementation might just be a adding speccs to load conditions

Even then, it sounds like you're setting up a problem if you're a melee, don't load ranged mechanics, and then get targeted by ranged mechanics because the ranged are all dead.

But granular support for multiple specializations (without being filtered by class) would be good.

Isn't it also inconsistent on how exactly certain healer classes are clasified? E.g. sometimes heal paladins/monks are treated as melee and sometimes as range?

yeah I guess speccs would be an overall better implementation. i could then just have a snippet-aura where i select all melee / ranged speccs and just copy it whenever I need it.

So far, mistweavers have never been treated as ranged. Holy paladins have been inconsistent, though.

talent speccs already exists as load condition so the only changed that would have to be made is making all speccs available instead of showing only yours
