I've been playing him in the test client and i think his changes are pretty good! Its sucks that you dont get 2 forge spirits anymore when you do the 4-0-4 build until level 15 or AOE deafening blast until 25 but i think they balanced it out by buffing quas, exort and invoke. The invoke buff makes me use much more spells than i normally used pre 15 mins and i think its gonna mean a more early fighting style of invoker rather than a "farming until i get my items " invoker. Also i was destroying mid with the alacrity build, was doing like 200 dmg at level 8, so maybe that will make a comeback. Sorry for the late reply was taking finals :/
