i'm at paragon lv 15 with my WW barb.
doing inf act 3 and 4 run.
act 4 is like playground because of the amount of demons and elite around with large areas.
act 3 more challenging because of elite with firepool, firewalker, vortex, ice and jailer. a lot of the time they just create the fire, vortex me in and jail me to death. I've checked even with high RA still kill us quickly. only way to get out is to maintain more chance for WOTB to dodge all of the jailer or ice. Usually gets very annoying when my WOTB is on cool down.
