Would you rather healers get more complex healing kits or more complex DPS kits?

[RitsukoSonoda]

I dont want more complex healing, nor complex dps rota...or many buttons..
I want higher HEALING REQUIREMENTS such has:
1) Bosses deal more auto atk damage
2) Remove self healing from dps/tank
3) Raid-wide dmg happens more often
4) Random damage spikes.
5) Mech that evolve around dispelling
6) AOE DoT DMG!

Yeah, I feel the kit's themselves aren't the issue and that the real problem is the battles/encounters/duties themselves with a small amount caused by additions to some non-healer job kits.
