Liturgy of the bell is a great ability.. in raids. Particularly savage, sometimes in extreme. The fact that WHM needs to take dmg for it to trigger can be problematic (usually works out though). The problems can be u need to use it at a different time (3rd flow in p2s), or does not do anything (healing a tank in dungeons where u dont take dmg).

Could potentially just be limited to magic dmg only, and ANY party member can trigger the aoe heal, or even better, all party members get 5 stacks and it triggers when they take dmg (i think the 1 sec rate limit is a good idea to avoid overheal and stack wasting). Guess what works like this. PANHAIMA! It even heals for a bit at the end, on a short 2 min CD.

Lilies: if u gotta heal u gotta heal. Still beats wasting mana on medica 1, and u get at least a lil bit of dmg out of it. However, dmg+heal skills on the rest of the healers r dmg neutral. So yeah, lilies should be too.

Im still not completely convinced by the 1 spam being terribad. Granted im an off role WHM, im instead kept busy by my slidecasts and figuring out where i need to use my instant casts to keep full uptime while booking it, or to squeeze in that extra GCD.

Im not sure y piety is still a stat that exists. Nobody other than WHM needs it. And those 3 healers r designed around not ever needing it. I think WHM didnt need it in SHB with the good old thin air right? So just remove piety already, have lilies restore some % mana or something (being dmg neutral and giving MP would be a nice encouragement to use the gauge).
