Just posting my feedback here as I am not in alpha.
Icecap- This is a big one, this talent will feel a lot less rewarding without the Frostwhelp’s Indignation Azerite trait which gave you a big aoe burst ability in Pillar of Frost and a lot of mastery to go ham in aoe. Frost will feel a lot weaker without it and Pillar of Frost specifically will become a chore to cast. Similar to Army of the Damned they should put that Frostwhelp’s Indignation into Icecap.
Unholy-
Please bring back the 6 second refresh time, it makes the class a lot more smooth. Also maybe like half a gcd when summoning because the ramp up time is only extended when you add gargoyle in and it was already long.
Those are the only necessary ones I feel, other really good changes would be to make Frostscythe, Breath of Sindragosa, Epidemic, and maybe unholy frenzy baseline as they are taken in almost all situations and just fill the voids in the classes kits. Replacing them with passives would mean your amount of buttons would not increase as well.
