Did some Normal ToT today, and my haste arcane build is awesome.
Burn phase is back with pretty close to instant mana recovery.
I'm doing around 20-30% more on burn, and pretty much the same for the rest of the time compared to 5.1.
My only concern is that the 2 second no CD evocation is going to get nerfed as it feels a 'little' strong

The key here is burn/non-burn is back. Getting similar total DPS to 5.1, but I can go burn like I couldn't in 5.1.
It also just feels better.... it doesn't feel clunky now.
