excog still is very hard to use despite of it's potency and duration buff.
always get killed off by my co-healer and the tanker themselves casts clemency.
when it doesn't proc, it is like 1800mp down to the drain.
then comes the tank buster. my co-healer pre-cast cure2 and it instantly topup the tank right after the tank buster, felt like my excog is not needed at all :/
