Leveled as BRD/SMN to 50 and fatehealed as SCH if no other healer around. On 50 Fc mates needed a healer for AK speedruns (and I mean really speedruns cause I got heartattacks as newly 50)... since that I played SCH over SMN...
WHM I had leveled to 50 in 2.0 and not touched since in 2.3 my static raided without me cause had a meeting. Came home was ninja invited to a T8 clear for a new member... SCH spot was taken so offered to go WHM (i80 relic lol) and we cleared. Had also a static on my alt and offered for one raid then to swap WHM/SCH to offer the WHM to relax... they decided to swap roles for good after 1 hour (wasn't actually asked but was a nice change) D:
AST I leveled as 3rd after HW release I quite enjoy it.
I still main SCH still and offer WHM/AST as needed for raids or just derp around on them ^^
Ur MP must suffer Adlo Spam never proven a good solution to me. If I heal I use Physick/Lustrate > Adlo else I would OOM pretty fast. Adlo is meant for shielding only... in dungeon no shielding needed so I may Adlo only if I feel generous.
(I admit I barely heal at all in dungeons cause too lazy and DPS uptime... so maybe thats y no Adlo)
