Is pre-buffing neccessary?

[VanilleFang]

Any buff is better than going in without.

So true. Which is why I will never understand people who find E4E "useless" or "unneeded". It is a free (no MP cost), instant cast spell that is off GCD. Even if the buff was incredibly minor it would still be useful for the plain fact that it is a free, instant cast spell that is off GCD. Where is the negative in casting it? It's not like healers have a rotation.
