When original wolves den came out healing was pretty fun.
Before quick-chat healing was pretty fun.
Up until shatter, healing was pretty fun in frontlines.

But now shatter is basically just a deathmatch of people splitting up and not listening, making decent healing nearly impossible in about half of the matches (especially on Maelstrom)

And The Feast is just angry DPS or tanks who split up or run out of line of sight, and spam anytime they die.
More importantly, the limited number of skills a healer now gets, makes it impossible to carry a bad party (as we could in the past).

There's a reason why there are so few healers in frontlines.
And why healer is insta-queue for feast 95% of the time (the other 5% is probably waiting on another healer)

PVP either needs a serious re-balance, or healers need some special rewards.

Frontlines needs a new "seal rock" (which required coordination of objectives, so that people were usually in the same spot) or similar game mode that isn't so reliant on hitting things (which seems to be all dps want to do half the time)

And the feast either needs rebalancing, actual ability to communicate with each other (no quick chat), or a limitation on the number of times you can spam "nice job" or "good game" as that's become the new shit-talking anytime someone dies.
