OF COURSE my players buy all thier attacks (and Defenses) at 0 END. As well as Make sure they are at the campaign limit for Dex, SPD, OCV, DCV, Damage Class, etc, etc, etc. No one wants to be the "Average" everyone has to be "Ubermenchen Ultra-@$$-Kicker Man" with all thier abilities maxed. One of the reasons I stopped running supers games for so long.
In my new campaign all PCs will have the Normal Cha Maxima DIsad. That should help keep Stat inflation down at least (although I expect to see a LOT of attempts to buy Stat as powers so that they are affected by NCM that I will need to step on). I suppose I could try a "Rule of X" approach. SPD+OCV+DC in Attack may not exceed....
