We just recently did Horridon 10 man with 2 healers. The raid make up was Paladin/Blood DK for tanks. Resto Shaman and myself for heals. The dps consisted of and Enhancement Shaman and Rogue for melee. The ranged were 2 Warlocks, a Hunter, and a Mage.
Now you may ask why this was frustrating and how does it pertain to wild growth?
Wild growth is limited to 6 targets glyphed, with 8 targets during Incarnation.
It hits these pets I know for sure:
-Army of the dead
-Wild imps (all of them)
I watched during this fight as my wild growth was placed on these above pets at full health over players with at least 15% missing health. The only thing that seemed to help sometimes was placing myself farther away from pets and closer to players. This is impractical.
I believe this issue, although not game breaking, is harsh toward a druid who has a limited number of targets to begin with. When 2 healing fights where there can be aoe damage, every little bit that hits a player is important.
What I suggest is removing any form of "pet" from targets that the heal considers if possible. Granted certain pets, if they die, are a loss of dps. Unlike a player, however they can be brought back without any other penalty then the time it takes to summon those that are summoned.
Those like wild imp and army should never need a heal to begin with, why are they targets for the heal?
I am sure wild growth is not the only aoe heal that hits these "pets", but for a druid being limited to 6(8) targets at a time is quite punishing.
If there are any other ideas or suggestions I am open to them. Just tired of seeing a swarm of imps or army eat my heals.
