Ok, first off I'd like to say there is no 'better' healer. Also, when you talk about classes, is most cases you can't really count their path, unless it's an obvious choice (like SK's *should* take blood, IMO and most others). Can't really county CM's either, incase somebody doesn't choose to get them, or doesn't hae fronts (say none in stores and waiting to be ordered in, idk)
Druids-
Their paths are:
1. A group double-stack heal with 3 tics total (2 on cast, 1 after, unless another heal is covering it up). Good for pulling aggro (when trying) in the sticky situation where you know tank ect. won't live with all mobs currently on them.
2. Get an FR DoT which also debuffs FR. Not sure on details.
Get invis, sow, snare abilities with DMG, DS, good AC/POW buff, form that gives STA/AGI and HP (heals for as much AC it adds), FR/CR buffs, FR, LR nukes, and some DoT's (not sure on resis). And of course, some evacs.
CM's they get-
Forms that buff CHA, POW and I forget the third stat but take away wolf forms, look on spells link to the side of the page. Group DS, Group AC (50 base ac added to druid for each one of the GRP ac buffs bought), their 51 CM's is a tree form with PoT buff and such, mixed opinion's on it, ANIMAL charms, and a updated rez CM at 40.
Shammy-
Their paths:
1. A better pet the merchant pets at, or around that level.
2. A debuff of which I know no details about.
Get invis, SoW, pets, CR and AR nukes, PR DoT's, STR/STA buffs, DEX/AGI buffs, STR/DEX/AGI debuffs, Bear form's that buffs STR/HP.
CM's they get- (I'm a lil foggy on shammy CM's, only got a sha to 17, DRD/CL to 30)
Debuff increases, a rex upgrade at 40, Group AGI/DEX buffs, Group STR/STA buffs, CM's that make forms buff for more, 1 STR/STA/AGI/DEX buff at 60, and their 51 CM is Avatar, (lvl's 33+ castble on) 150 STR/STA/AGI/DEX 1500 HP.
Cleric-
Their paths:
1. 3 sec cast (23 recast) single tic heal on target for about as much as your closest lvl heal heals for
2. FR/CR/AR/LR/PR/DR (not 100% on PR/DR seeing as they already get PR/DR buffs reguardless)
Can wear most plate armor unlike DRD/SHA, get group insta heals, good AC/HP buffs, DR/PR buffs, better rezzez's then DRD/SHA/NEC, AR nukes, undead nukes, undead debuffs, amd procs caster on MoB that hurts them when attacking somebody.
CM's-
Group AC/HP, CM's to reduce hate gained by group heals, group DR/DR buffs, AoE undead nukes, improved mob proc spells, and some CM's to mess with resist path which all confuses me. Their 51 is temperary invulnerability.
When compared to eachother:
drd sow- sha sow- cl plate armor-
drd invis- sha invnis- cl grp heals-
drd cr/fr buffs- sha str/sta buffs- cl dr/pr buffs-
drd ac/pow buffs- sha agi/dex buffs- cl hp/ac buffs-
drd snare- sha pets- cl mob procs-
drd nukes- sha nukes- cl nukes-
drd dot's- sha dot's- cl undead nukes-
drd evacs- sha debuffs- cl undead debuffs-
I think that about covers it for comparison with NON-cm abils.
All their heals are equally modded bye CHA so no one class has 'better heals'
