Just read through the preview.

I'm also using VQ build now, but I feel like they are doing the right thing to nerf VQ. Coz I really hate having to run 4 skills on cooldown all the time, which really removes most tactical options.

Which the base mana regen increase it should be viable to spam rain of toads instead of acid rain for tank doctors build. Downside is smaller AoE and lower damage, but they did mentioned they're gonna buff the damage of many skills to except splinters/bears.

And I'm really interested to see if pets are indeed viable. Can't wait to try.
