Certainly there are ways we could limit it, if the consensus was that it needs it...we don't have to have +15 heal bracers, as there are now (code it differently or some such), can limit the + to three, such as umd....
i understand the thought of 1-1 being overpowered, and mebbe it is, and you mention, as i understand your thoughts, as it basically being a freebee (which i think it should be, even if only minimally) and easily added to what already exists in game...but i know i like choices...
if my heal skill will allow for a +10 bonus to healing amp, that's one less item i don't HAVE to wear, or i can and it hurts elsewhere. Them's the choices i like...just as you said at end, make some of these skills that simply aren't used and really make me choose my skills every level, instead of just balance/swim-done.
