Do I have to do anything to make Selene work?

[Cynfael]

Selene still does decently on sic, especially if the fight has no raidwide esunable debuffs. If you don't know a fight id rather have as much uptime on a fight as possible for fey wind than save it for particular periods of burst unless its necessary.

I don't find that it's as much a matter of saving the CD for burst even as it is a matter of not allowing her to waste it by throwing it up right before the boss is about to jump or the last mob in the pull is dying.

Left to her own devices she can actually achieve less uptime on Fey Wind due to her AI peculiarities. A good micromanager will trump sic for sure.
