Lets see.
I hadn't realized the dropping the magic item use limit was so popular. Chalk me up for that one.
The other major one is the limit on the number of immediate actions you get per round. I haven't bothered auditing this one on my players, and I let the monsters do it as well and so far it hasn't been an issue. If there is some balance reason for this restriction I'm not seeing it. Arguably it makes immediate actions more powerful, but so what? Players still have to pick that power at the expensive of others. Who cares if they are geared-up to be super reactive if that's how they want to play. Otherwise we stick to the obvious: you still only get one opportunity action per enemy at a time.
To me, both of these rules fall into the area where they take up too much head-space to be bothered with.
I'm also seriously considering rewriting "insubstantial" because I think the mechanics for it are poorly done.
You are generous if you allow any number of immediate actions, your defenders must love you. I would if I played a defender at your table.
And just a minor rules correction, it is one OA per turn. Or did you want to say you ignore that, too.
