Beast Cleave - damage increased from 30% to 50% of original damage.I'm not sure I'm happy with the number -- as it seems a bit low -- but I am happy with the sentiment. We've certainly seen very rough numbers thrown around before. MM and SV buffs were stated at nice high round numbers and then got cleaved down ... to lower very round numbers. The "50% of original damage" value sounds incredibly round and subject to change. We'll have to see which way it goes. If it goes up then we will not be compelled to have an SV spec. If it goes down or isn't a noticeable change to our AoE capability, then we may feel that is a requirement. Beast cleave is one source of our AoE damage, but hardly all. So a +20% to it may not be meaningful.
The Beast Cleave change was because we felt Survival's multi-target damage was too far ahead. We don't mind good AE as a spec niche, but it shouldn't be so high that you feel like an absolute idiot for not swapping to that spec.
FWIW, I either have my alternate talent as either a pet-tank setup or a PvP setup. I haven't done too much with either since MoP, but I am starting to line up a pet-tank suit. On many somewhat challenging boss fights I'm swapping talents or glyphs -- but never specs.
