Lets talk warriors :)
Zerker really is all you will need in pve. Full zerker, scholar runes and a good, knowledgeable group. If you like running newer players, make a soldiers set with hoelbrak or tanky runes.
My warrior is Miran Cross, 3 ascended sets, Zojja/Chorben/Ventari. I run full meta in dungeons with a experienced group and really, it’s just fine. Know your fights, learn to dodge killing hits and rotations.
And now, always check what another warrior is running, build wise. Only 1 should be running Phalanx, the other should focus on personal dps.
