Eh, being a healer isn't so bad as long as you have a good partner.
Using FlyFF as an example:
Me being the full-support ringmaster, my partner being... oh let's say Blade, and we're taking on a giant together. In the middle of the fight while I'm spam healing him, and he says 'rebuff', I know that he's too busy to type properly and with manners because in that extra second it takes to type 'Rebuff me, please' he could die so I dont get mad because he isnt being polite.
It's usually best, if you're starting a new game and planning on being a healing class, to bring a friend along so you two can be partners for as long as you play and you dont have to worry about things such as looters and people who only type in 'leet-speak'. Being a healer sucks the fat one, otherwise.
SHORT FORM:
Healer class isnt bad if you have a good partner.
EDIT:
Typing all that has started me missing my gaming days. .
