It wont increase grinding time as you will be able to use AotH 90% of the time allowing you to kill faster.

Someone on the forums posted a video so ppl can understand how quick the regen is.

I don't think they made this change just to make grinding harder for us. In a long raid boss fight, this will solve almost ALL of our mana issues.

Look at it like this. Say you crit for 2k. Good times, eh? Well, with this on, the damage cuts to 1k, but you gain 1000 mana on the spot. Not to mention the fact that critting can only get easier come Wrath.

The Aspect Mastery talent will reduce the damage loss to 40% and I'm sure there'll be a reworking of the Viper glyph to make it even better.

Really, there might be a slowdown of grinding, but we also don't have to cut time off to get a drink, either. Low on mana, just switch to Viper and shoot some things with your pet tanking. Boom, you got more mana. And with Hawk, you would take down the mobs faster than before anyway.

Ah, I still have my raid virginity so never thought of that, and I forgot about the Talents could reduce the damage reduction.

*is still a noob* >_>

lol that will be so nerfed.. with that hunters got 0 downtime when they get full mana back in 3 seconds

The whole point of this change is that you can use AotH whilst grinding. When you're a little low on mana, switch to AotV and regen it all. This therefore = Zero Downtime and overall more damage done.

Plus there is no mention of whether or not you're pet's damage is effected by Aspect of the Viper.
