I've more or less finished my character, but there are some points which I'm not completely sure about.
As I wrote in the ad, I've given more weight to the backstory than pure optimizing, but I'd say it's pretty optimized anyway. I've never played this type of controller before, though. I've always relied on forced movement, immobilization, slowing and the like to do my duties. She's practically made to take Psychic Lock at Paragon -- all her powers are psychic damage.
I'm very unsure about the level 1 daily. I might still change it to Living Missile, sacrificing some fluff. Perhaps she has some hidden talents she's not aware of.
As for defenses: Fortune has a starting AC of 16, an immediate interrupt which gives her +3 on one attack, an encounter item power that lets her shift 5 as a move action, and the Memory Hole power (makes you invisible to one enemy you hit). She's built on the "offense is the best defense" idea, with maximum +hit and targeting the usually weakest defense of melee-fighters, Will.
I am not, however, completely sure it's a good idea to rely on that alone. I could take Unarmored Agility for +2 AC, sacrificing +1 hit. The problem with that is that +1 hit is always (as long as you attack) useful, while +2 only helps when someone is attacking your AC. It's not a good idea to have a super-defense controller that can't affect the enemies much.
I could also take Staff Expertise rather than Orb Expertise. I have no use for the orb expertise bonus effect: +1 on forced movement. I do, however, find the orb I've chosen incredibly useful -- basically an extra encounter power + initiative bonus. Staff expertise, on the other hand, negates all OA from standing in melee, which is very useful in cramped quarters, difficult terrain, or when we're getting overrun. Fortune is pretty much useless if she's surrounded as she is now. The main reason I chose orb expertise is that I found it much easier story-wise to conceal an orb rather than a staff. If any of you have a suggestion on how she could have smuggled in (and kept) a staff, I'm all ears.
