Hunters are soooo useful in pve. The 4 shot golden gun can take out a swordbearer almost singlehandedly. One shot for the oracles. Bladedancer is ridiculously good for crota for many reasons. Going invisible to save. Being able to catch up during dark part no matter what. Underrated imo. Titans are useful, but personally find them the least fun to play. Warlock is most overpowered tho.
