As long as all options are unchecked so it's not autoretaliating i've never had a problem with it.
Wish I could say that, The only thing ever toggled on my fairy is follow, and they don't even do that very well. In siege, if I have to run from one tower to the next, by the time my fairy catches up the battle's over.
Commonly heard in siege there's a priest with invis in center, I see a fairy wandering around' Oh, that may be mine, I ran through there a few minutes ago....
The fairies are fun though, fairy duels, and with heals they can (slowly) take out a lot of mobs
