I’m not seeing why that, in particular, is a problem. If I take something really powerful, for a lot of points, of course I end up with fewer points to take other things. That’s inherent in any point allocation mechanic.
It’s different if one of the really high-point things is actually less powerful than other high-point things. But if I spend 1000 points to be the proverbial one-trick pony, well, that was my choice, and I haven’t been wronged by not having points left over for other tricks.
