I personally enjoy Drk and War more than Pld simply because holding threat is far easier, freeing me up to do other more constructive things like Dmg, healing, dmg mitigation, ect. I feel like when I'm on Pld, i'm being constantly rushed to keep up with the DPS, that I'm never ahead enough to be comfortable and that I'm constantly out of TP if I'm pulling too quickly. I'm by no means the best tank in the world. But since all 3 classes are aesthetically pleasing to me and perhaps because of my own play-style I enjoy War and Drk far more. This decision has nothing to do with High end content and how much better or worse one class is to another. They just feel more fluid and well thought out. My pld is only like 53 or something, But I quit playing it because I wasn't enjoying myself. Imo just pick the one you enjoy the most. It's competent, just not my jam.
