My new main is a Paladin, but I have a serious issue with the often-touted "Holy Trinity"... DPS + Tank + Healer.
My problem is with the "Tank" concept itself. In real life, a Highly armored low-DPS combatant would be ignored and saved for last. In MMOs the enemies swarm to the tank. It's stupid and does not make sense. Although it creates the Holy Trinity strategy, I think it would make more sense to have flexible strategies. There are a lot of problems arising from the Tanking concept in Neverwinter. Constant debates over how much DPS they should have, problems with 'aggro-pulling' & 'threat generation', problems with assumption of roles, problems with how in the fantasy campaign monsters stick to tanks like magnets... yet in PvP the Tank is avoided like the plague. I think its time that the concept of 'Tanking' be re-invented.
