The tankiest class in the game were sun singers with radiant skin and a strength build to keep their over shield on as much as possible. Good bye tanks in Destiny. This is why the balancing needs to be different. In a team based PvE game there needs to be extremes i.e. tanks, buffs, CC, single target. In Destiny as it is right now we just have a bunch of mediocre subclasses trying to struggle their way through events all pretty much capable of the same thing.
