Chieftain looks like it excels very well in PvE, especially soloing greater content then before. However, I think they lack in arena with no stun. unless you do bear hide before stun combo, will likely get eaten alive in cloth armor before stun lifts. The other thing I think they lack is true role within parties for PvE content. There are better dmg to bring and obviously, better support. Even with prioritizing those abilities that do damage, Chieftain is still mediocre to other classes and require melee range with little skill points left for surviving in cloth.
