I'm level 76 on my main and rngesus has not seen fit to bless me with a tempest roar, crone, or vasily's, so I've been using the same pulverslide build since around lv40.
My build is basically NF capstone with symbiosis and nature's savagery to reduce all of my CDs and run around with constant tramples, bulwark, hurricane, etc, all while dropping pulverize shockwave bombs. It works pretty well and is fun and satisfying, but I'll admit after close to 40 levels of it I'm kind of bored.
For the other unlucky souls out there, what have you been running without uniques?
The straight pulverize build can still work without uniques. I switched mid 60's from trampleslide to pulverize. You have to alter it slightly for the spirit issues, but most of the power comes from the paragon boards I feel. I've only found one vasily's and that was around 79/80.. Truthfully I'm kind of bored of it too, I usually run a couple of NMD's or helltide then get bored. Really just waiting for the season to start so I can roll a new class.
Barb is pretty limited imo. HotA is fun, but upheaval is weak and looks dumb, never liked ww, and bleed builds are the exact opposite of what I look for from a barb.
Necro has a ton of good options though. Sever is a fun melee monster, spear is a complete wrecking ball, blood surge will be awesome if it's ever buffed / supported... I'm not big on minions or bone spirit, but still, necro looks like a solid pick.
Druid has a ton of build variety, I just hate how so many of them are unique locked.
