Just because I am Soraka, does not mean you dont have to worry about taking damage.
Not a lot frustrates me more than supporting a team who either can't dodge skill shots or goes too aggressive, dies, gets mad, and then blames me for not healing them. Before her rework, yes this could be more my fault, but since her W no longer heals for quite as much and her Q isn't instant health, spamming heal hurts me much more than it heals you. Plus, there is a cool down which is short but not spammable to the point of it always being up, partly because each heal costs 10% max health. Yes if my Q's passive is active you heal for more, but that is reliant on landing the Q in the first place (if you kill everyone while tower diving then I can't get the Q's passive to boost the heal to counter the tower damage). Also, unlike many popular champions right now, i have no movement abilities that can hop walls, so dont expect heals from outside the dragon pit when you dive over.

: Heal me already
: You do realize I'll go oom if I touch W like...twice, right? I can't use it for patch jobs.
