This is rather self-serving since I'm currently using the theme but the level 1 summons can cast daze two to three times before doing anything, which is... troublesome, since daze is limited by HD.
Rather than defending my character, they stand there and cast daze, which has absolutely no effect on the creature they're trying to defend me from.
My suggestion is this : Remove daze from the spells they can cast, replace it by something else like flare or even, give them a single casting so the player is not forced to wait a few rounds to get his summons in the battle.
Of course the best suggestion would be to remove the HD limit on daze!
Hrm... I'm up for remove the HD limit on daze and reduce the time it affects the target, making it a spell most used to disrupt something instead of keeping someone out of the fray.
I would suggest making use of the Control Companion tool if you wish to get your summons into combat more readily, rather than waiting for the AI to simply cast what spells it will :)
They'll only try to cast daze once now.
