I'm glad things have gotten better, DL -- sorry I bitched at you; the refrain wears a bit.
Mind, the last resort -- start your own game -- is actually pretty good, though admittedly harder in a town with 4700 (and as a NYC native/resident, I'm hardly one to sympathize, though the City can be awfully empty at times, particularly for a geek).
Part of what's going on is that when you present the game as abusive, and are only arguing about -levels- of abuse, the right answer typically -is- "just get out of that situation already!"
That said, it sounds like some of the classically grodnardly issues (eg, your GM using a very sim approach to treasure and not quite realizing how much things scale up as you go up in half-tiers) are resolving via education, which can be useful if the GM really is "set in his ways" rather than really out to screw you.
Back to the thread (ish):
I do generally play armor of repulsion (which my Isa Sunrise -- my Deva Avenger/Battle Engineer uses) as not interrupting movements (except charges, but even there, I don't mind if the GM continues a charge; every square of (non-forced) movement has still carried the character closer to my character; if I really want to hose them I can stand in difficult terrain with activated armor of repulsion and antipathy gloves and be effectively unchargable by opponents that don't have reach with a movement of less than 7); the problem is the ruling set for readied actions (where you really -have- to be able to use an Immediate Reaction on each square of movement, or you can't do the whole "I knock prone the first enemy I see" or use readied actions to get a hit on foes using flyby/moveby attack with terrain to be untouchable. I also think the armor is more than a bit overpowered if you make it "when an opponent ends their movement adjacent to you" (although, yes, it actually makes it a -useful- item daily -- but item dailies should be on the same level as encounter utility powers, -not- on the level of daily utility powers or side effects of nearly-broken daily attacks)--though slightly underpowered [if still quite useful] in its current form, read strictly. Making it a 1/opponent's turn free action is probably about right; that would basically make it a stackable Antipathy gloves that consumed an item daily, rather than a stackable but far -weaker- Antipathy gloves.
