Right now, 3 of the 4 tanks are effectively healers. They each have, every 25s, one button that is a really good heal for either themselves or another party member. WAR effectively have 4 benedictions every 25s. GNB have excogitation every 25s (actual Excogitation is a 45s CD). PLD have a really solid regen every 5s at best, but in practice I would not be surprised if it came out to be every 25s-ish. In practice, this creates a really bad situation where 90% of each healer's kit is redundant or useless every 25s for 3 of the 4 tanks.

While the memes are fun, the reality is not. I had a run of the 83 dungeon where I, as a Sage, died at the beginning of the fight. The GNB was able to continue the fight using nothing but their kit to heal the party while I watched from the sidelines. In the moment, was pretty awesome to see, but this is possible in any dungeon (possibly even the new raids), with any of the tanks except DRK. Right now, healers have a high chance of not having a job to do because 3/4 tanks can heal themselves and others just as well as an actual healer.

As a player, I should not bemoan seeing a DRK in a duty. I should not feel bad just for leveling a DRK simply because it has not self heals. It's okay that tanks can heal themselves, but the amount of healing they offer not only to themselves but also to others is simply ridiculous.

And if the amount of damage in certain duties is so high that it needs those self heals, then the problem isn't the strength of the tanks' kits, but the weakness of the healers'.

IMO, the heals on WAR, PLD, and GNB should be nerfed, and healers should get some buffs to their oGCDs to compensate.
