Possible Rule change, Imput wanted.
I agree with the PITA to change this sort of thing mid-stream. It, essentially, would require semi-rebuilds of characters, especially ones who are more mentally focused.
Honestly, WRT attributes, I think Palladium is terminally broken, especially in games where you're in mecha. The only attributes that matter in combat are PP (only if you manage to get it to 17 or higher) and IQ (in only a minor way, and, only if 17 or higher). Out of combat ME, MA, and PB can make a difference too (but still, only if you manage to get them to 17 or higher), but PS and PE pretty much serve no role at all for most characters.
In order to fix things, you'd really need to use bonuses/penalties that are more similar to d20's setup where no matter what score you had you almost always have something, and you'd have to find ways for some of the attributes to matter again. Mechas could make natural PS "mechanical" (thus doing megadamage), and, depending on the mech, give a bonus. For PE it could replace PP in giving a bonus to roll with impact, and maybe parry? Not really sure, since this is the first I've thought about this whole situation. ;)
