It's ironic that pvp has healers with dps kits and they also have more GCD healing to do, and everyone in that mode has a powerful self heal. I do realize a lot of it only works because it's pvp though.

Tanks can barely tank the same since they're squishier and the best they can do for enmity management is being a nuisance that's harder to ignore, damage comes at any moment in any amount, dpsing helps the objective but isn't the ultimate goal, and our skill sets are far more limited.

This in contrast to pve where tanks are extremely tough and enmity management is largely just having a stance on or not, damage is scripted and spaced out in very specific intervals, burning down the enemy's HP is always the objective, and we have a surplus of healing oGCDs.
