In all of my time MMOing, the most difficulty I ever had tanking was this game's level 15-20 gladiator tanking. New players in the group go mad with dps and heals, generating more enmity than I can put out. And of course, my own enmity is total crap without the blind on flash. It got INFINITELY better after level 20, but up to that point? Brutal.

My main in this game is a healer- scholar to be exact, and I cannot express how much better of a healer I am because of that small amount of time tanking. I always knew that overhealing generated enmity, but I had no clue how much until I experienced the frustration of tanking with a conj who Medica spammed.

The first time you realize that, as a tank, you simply cannot generate as much enmity as an overhealing healer, you realize just how important it is to heal properly and not just throw heals out at random and them blame the tank when you get aggro.
