-Without UtH, they are an aggro-style deck that gets trumped by any other aggro deck.
-With UtH, their entire strategy revolves around 1 card, hence why it's considered "op".
-In Arena, Hunters suck simply because their strategy revolves around specific cards that if not given in the randomness of arena, makes them suck.
-Because they revolve around one strategy, they are easily countered by advanced players.
I've been playing Hunters forever, and I decided to actually try in an attempt to balance Hunters, just because Blizzard doesn't really know what to do. They even admitted this by saying they don't know what to do with UtH, but decide to nerf Buzzard which is just strange.
After playing Hunter for months since I've gotten beta, here are the changes I would make. I'd appreciate any feedback.
Unleash the Hounds
-Changed to +1 attack and Charge this turn only. (The charge won't matter after that turn, but this will make it a bit more balanced).
-Change Power from 2 to 3.
-Change cost to 6.
-Change so that it only attacks an enemy character.
-Change cost to 2.
-Buff this. We have a 1 cost spell that deals 2 damage in any situation, but this costs 3 to deal 3, and 5 if we have a beast? Seems grossly under powered.
-Change so that instead of discarding them, you shuffle it back into your library.
Just remember this is to make Hunters balanced. Not overpowered or underpowered.
