If hybrids are overpowered right now, is that just because putting 100% of your points into Memory is better than putting them into other attributes?

If that's what you mean, then it seems like the key problem is an imbalance between Power attributes (STR/INT/FIN), Support attributes (CON (defensive support) / WIT (offensive support)), and the Versatility attribute Memory.

I think we all can agree that a build which puts 100% of points into Memory should not be the most powerful build.
