There is a split between "too complicated to use" and "OMG!". The too complicated to use people have mentioned... grapple, turning, and the like. They're not unbalanced, just not likely to be used because they're a pain.
As for good 'ol Mordy's Disjunction... we've kept it as is. My abjuration-focused mage has spent a ridiculous amount of money on defensive items, and is waiting eagerly for a monster to actually cast one. Given that we're at the end of the campaign, doesn't look like it'll happen... but that's because we beat the nasty mage on initiative last week
I'm a big fan of the players talking over things with the DM. My DM took a look at a couple of custom items (combinations, mostly) that I proposed and said "What the hell?". I told him they were anti-Disjunction prep, and his response was "Cool, that means I get to toss one out!". It's all about the communication.
... says the mage who _wants_ a disjunction. Please, mommy, can I have one for my birthday?
