Usually I play SCH in pvp but sometimes (expecially after the CS removal, rest in peace ç.ç) I play SMN and I really enjoy it, BUT

Misty veil is an ability thet I'm probably understimate, up to now I use it when a BLM focus fire me and I'm able to see him, and when during node I try no nerf healer rande of healings.

But up to now I don't see any decent output, the time loss due to switching target to put it and return to the target to attack make me doubt about its utility to be honest :/

So I ask you, how do you use it?
Do you think it's a valid skill and have you enhanced it?
(If yes, do you think that it's a good choice? XD)
