After your fully spelled and got some nice ranks and maybe some gear, so your rolling 10+heals, meming in single tics and have over 550 hp steelskinning, etc - Love them for single person dps and exploring, but i roll my clerics like tanks.
Hate:
Fully spelling up such a damn pain, and thats when you have multiple clans of people helping try to spell you up.
Grindy, and for the value unless your brute forcing a fight which you have to single or double heal each round for a few minutes straight. You can probably just roll with a shamy / druid in the group.
Did i mention Grindy, and also its a one sided role focused on healing for the most part. when compared to the full spell list.
Its hard to resist fully scripting / triggering / aliasing your way through this roile, cause spamming group every round, and scanning and doing math on the massacre per groupmate vs obliterate and their max health and who needs a heal first vs when your lagged, vs primary heal and 2ndary or tank heal vs group heal.
Would be nice if:
There was some variation over direct instant healing, and healing over time.
The output / there was some command to run to help track in real time your groups HP's and debuffs etc.
Every spell you study, is a chance at something you dont have, no more recognize or nn. This is so aggravating especially at higher lvl spells.
Adopt a WoW style of spells and types of clerics, or atleast look at the mechanics and setup on how they do it. Not quite like magic users and the different robes, but maybe something along the lines of hey DPS cleric, Healing Cleric, PVP cleric.
Condense down all the spells to the core function spells, healing, prepping, damage.
Make alot more spells divine, so i dont specifically have to memorize c food or water or restore etc, managing your spellbook i think shouldnt matter as much just so long as your memmed. Maybe just have a memming debuff when switching roles from healing to damage or whatever for a handful of tics. And do away with managing a spellbook entirley.
Crazy:
Would rather have classless characters, or multi class characters and i could just swap roles as needed, and grin the skills / spells as needed without having to change which character im logged onto.
So i dont have to grind my way on multiple characters multiple times, to and through legendary.
Give them alot more xp for healing group mates, just like melee gives xp for hitting.
And if everyone is going to script / almost fully automate this type of character anyway, why not make the skills / spells that way in game. (Setup healing target priorities / roles etc)
