For one, in case people missed the VOD of an all Tank EX1 Clear, look it up on Youtube. They probably do need to nerf some of the self-healing on WAR despite it already having basically all the self-healing in the world that they could throw on themselves among other CDs(and one that's 25s, no doubt).

I generally think that Tank healing feels high only because of WAR's high potencies and PLD's self-sustain, whereas GNB doesn't have as much outside of HoC and Brutal Shell and DRK? Basically has next to none and relies on shields. Thinking about it, this is lopsided in terms of how tanks feel to run when it comes to their CDs.
