Difference between races for Healer?

what's the difference between races on healer?
anyone is more for pvp/oly/pve/mass pvp... ? what about reuse you guys always talk about?

 

are you asking about races or classes? because human can be shilen saint, and dark elf can be eva saint. :d

about classes:

oly:
se > ee > cardi

se has biggest m atk so easier to win more tough matches, also the mp consumption on passive is good.
reuse is also a bit better than heal power. cardi hasn't really anything good at oly compared to before diversification...

pve:
se > ee/cardi

se has single target rebirth also is very nice for pve.
the other 2 are more or less even in pve: heal power vs small reuse advantage.

mass pvp:
ee/cardi > se

se doesn't get much useful there in my opinion, reuse on ee is good for faster brilliant purge and cardi adds heal power to the party.
