I logged in to test a thing or two. Magic feels the same - still swimming in adren. I've not got the new Ranged gear, but I've heard from clanmates that it's cracked. Melee's apparently better than Magic thanks to the revamped Leng specs/passives. Necro had a slight nerf.
Overall combat feels better. There's a gold tint over keybinds as you hit them which should be helpful for people trying to learn strats from vids. I haven't looked into ability changes and damage rates in depth, and I'm still uncertain about Eruptive's play. Most poeple I spoke to about it were still using p6r1 + as4e2. The news post made Eruptive sound decent, so I dunno. We'll see in a week or two.
Edit: forgot to mention hit potential change is huge for offstyle abilities. Dracolich has an anti-switchscape timer attached to it, but now that wand/orb will 100% land a Smoke Cloud/Tsunami, it's viable and easy to pull off.
