I haven't really run into anyone that doesn't like it. The only person that had a problem with it was one who got a bit upset by the errata to Aura. Then again the aura change went into the errata anyway, not just UP. People don't tend to like something that tones down something they were exploiting.
You know, you may as well just mention me by 'name' Shal.

I'm not really convinced of the value of UP, and I think that (mechanically, at least) the quality of each M&M book following the core diminishes.
Btw Kain: what's pricier? The UP book price, or the cost of Elasticity in UP?
