I prefer Selene in raid. My melee also request I not use her sksp buffs. Sometimes I sneak it in anyway.

For dungeons I use Eos. With her buffed hots up I can spend more time in clerics while she keeps up the tank even in big pulls. Me spending more time in clerics makes the dungeon go faster than Selene would allow with only rouse to help me out. Eos us also very efficient at tanking adds for boss burn.
