Do you know why DPS is the meta of the game? Because this game is about depleting boss hp bars. The faster you deplete it, the more efficient you are. Even if DPS checks aren't a wipe inducing thing, this very basic game mechanic remains, and DPS will remain the rate of 'efficiency.' When the needed level of survivablity is reached, everyone will choose 'fast' instead of 'slow' when given the choice, and it will be the metric of 'skill.'

There's only a few ways to steer away from the DPS meta: 1. either completely redesign combat skills to give defensive abilities an offensive aspect (eg. increase vulnerability stacks on boss whenever mitigating damage or healing) 2. redesign the battle system so that hp bars aren't the main thing and battles would instead be won through some special conditions, or 3. tanks and healers are simply unable to do, or focus on, damage at all.

Arguably, the easiest way to totally kill the dps meta would be taking away all DPS stances from healers and tanks, but then you would have to argue why taking a meaningful gameplay choice would be good for the game experience. In my opinion, you would have to replace that choice with something else, just taking a feature away would be loss of gameplay elements, making things more boring for the player.
