Druid bunker
I mean it is kind of obvious that the most viable druid builds actually utilize the sustain in some way. Having fun with a celestial version. Not enough damage to kill deticated bunkers but I score about 400-500k per match which is quite something.
Bunker does not work in this game where you have to do a minimum amount of damage to get rewards.
Also you have to kill players to get rewards in other game modes.
Bunker will leave you without rewards while the rest of the players will get the ascended gear or the precursors from drops. I don’t think your teammates will share their loot with you.
