Re: Requires another power limitation?
There's already a system like this in place for Martial Arts - in 6E1 it discusses that if you buy any Martial Arts you have to get at least 10 points worth. Additionally, HSMA talks about optional systems for ranking martial manoeuvres - essentially, the idea is that you have to buy a certain number of points of "low tier" manoeuvres before you can get higher tier ones. It's discussed as a campaign ground rule - something we, as GMs, can just enforce. That sort of thing is okay in HERO.
