Do I have to control Eos?

[Pells]

Maybe it's my Selene that's not responsive to my orders, but the fairies always takes 5 secondes to do what i tell them to do ( except if she is not doing anything at the moment, but if she wants to heal someone, she will do it before listening to your order ), so unless you predict the move you must silence, it's very hard.

If there's a delay, sometimes it's because Selene will need to move to cast her silence. Her cast range seems to be a good deal shorter than ours, but if you've placed her properly she casts right away.
