Meta characters still remain the same. Sunder doesn’t change end game gear too much, but significantly helps ability to clear solo without needing infinity. Dmg to immunes even with sunder is poor, so it’s not recommended for mf. Most people on this sub forum play single player.
New viable PvM chars are Nova Sorc, fire builds (hyrda Sorc, Druid), FoH din, martial arts sin, and mid game/leveling melee chars.
Hdin and Blizz Sorc still top the charts, however.
