Legion Pet Battle Tuning

We wanted to outline some of them here for you, so that you have a thread in which you can talk about this with us. As always, these are changes we’re testing, subject to further change, not final, etc.

Undead racial
During its invulnerability round, the active Undead pet will now do -25% damage. Developer note: The Undead racial ability has been one of the most powerful, and this change should help bring it in line with the others.

Frog Kiss + Sleeping Gas
Now has a 1-round cooldown. Dev note: The ability to chain stun opponents (until resilience kicks in) simply feels bad. Rather than a blanket change to resilience, we’re trying a surgical change to one of the more aggravating aspects.

Thunderbolt, Avalanche, Grave Destruction, Carpnado, Arcane Storm, and Psionic Strom
Base Damage reduced by approximately 15%Thunderbolt
Will now have a 5-Round cooldown, to match the other abilities with similar damage and effect.Cleave
Added 1-round cooldown Dev note: AoE abilities are very powerful in the current battle pet metagame, especially “meteor”-type abilities, which are quite effective against both groups of enemies and single targets. This should bring them closer to their intended power level.

Graves
Clobber and Bonestorm slots swapped Dev note: Graves has a bit too easy of a time damaging the entire enemy team. Though we see other setups with Graves, it’s been too easy to AoE, and a bit too powerful among AoE pets. We are wary of opening up additional new Graves combos with this change, and we’ll be testing this closely and reading all of your feedback.
Graves’ base stats changed: At level 25, Graves’ Speed will now be 244 (was 211), Power will now be 297 (was 314), and Health will now be 1587 (was 1668). Dev note: Graves’ base stats, along with the Undead racial (which favors slow pets), made him an unfortunate opponent to play against. Combined with high AoE and Consume Corpse, he had very few downsides. This change should help bring his output in-line with other, similar pets.

Overall, this constitutes a triple nerf to Graves. However, depending on your ability choices, you may consider the Clobber/Bonestorm slot swap an improvement. Please feel free to leave your feedback in this thread, and we’ll be here reading (and responding where necessary).

Thank you very much!

Is there a way, even if we can't transfer characters, to copy our pets from live to alpha? Pretty hard to test some of the changes without actually having full options. Or at least "premade" pet battle teams?
I'm looking into all of this. I'll get back to you here.

I like all the changes here. I'm honestly surprised they didn't touch the self healing. Nature's Ward and ESPECIALLY Photosynthesis/Sunlight combo is pretty OP right now. Especially now that Undead pets received a nerf and Graves got triple nerfed.

I don't mind these changes, I have a cleave/undead team but just because I want to blitz through that pet battle weekly. Graves is fun but when you're either facing Graves teams or anti Graves teams it gets old.
