That Which He Does Not Play

[Absimiliard]

My personal opinion would be that GNB is the best tank overall. It's got good damage, some self-sustain, strong mitigation tools, and some nice utility besides. DRK dominates in terms of damage and raw mitigation, but those are all it has. It ends up feeling terrible to play (and heal) in dungeons due to its seeming hyper-focus on those two things, while GNB can perform all content at all levels without issue.

WAR is held back in high-end content by its relatively low damage, and PLD is crippled overall by a combination of not fitting the current two-minute burst meta (although this is likely to be fixed with the upcoming rework), lack of self-synergy (hopefully also to be fixed), and the weakest personal and group mitigation out of all the tanks.
