The warlock *feels* much better
After this patch went live, I hopped on to see the difference. Had to make a few changes, but running with an echoing strike warlock definitely feels more like how Diablo 2 should be. He's still strong, but instead of everything dying in one shot, uniques and champions take a few now. I am still comfortable enough that I don't worry he's going to die in every room, but I also have to pay attention.
This is all on a warlock that is horribly tuned. I have wasted skill points (especially now with the patch) and wasted stat points. I don't have a great offhand item because I was using a Spirit shield. I'm now using a book that doesn't really fit the build, and some of his gear is just for magic find. With a few adjustments and maybe a respec, he'll still be the strongest character I have. Just appropriately strong now.
I'm curious how others feel, especially those playing different builds.
