A little bit of almost everything, but not everything.

Healer classes; what the actual.... I have been in a situation where there were four DPS classes and were unable to kill a single healer that had extended too far into enemy territory. Literally a different type of Tank that also has the option to use Medical Kit and having 100% healing on themselves. Why?

If not, give something to a DPS class such as melee DPSes to apply a debuff to healer classes.

PvP is, or was balanced around The Feast, not Frontline. The debuffs you are suggesting already exists. They are applied by tanks and other healers.

But everything will change with 6.1. The Feast will be removed and replaced with Crystalline Conflict. PvP will then be balanced around that.
