..... part two
So you might say "overequipping" is unfair to some classes. Take NTs for example. They rely on their ability to dish out damge through their offensive nanos. So why not try to change the system in that way that you calculate debuffs different than "normal" skill lvls. Say a NT is buffing himself up for a fight and then he is able to use is best damge nano. So now he gets debuffed; why not just make him able to use that nano with reduces effectivness (similar to weapons). Same would be applicable to healing nanos for example. This would even out the current system a bit I think.

addendum: umm why do ya think NT have GREEN nano resist, so they're less likely to get debuffed anyway

But it is important to understand that not everything has to funtion in similar ways (with limited variety of development) to yield a balanced result, meaning a balanced game, in the END.
Take Metas for example they do not get to "overequip" huge guns but still they ARE very competetive right now by using pets way over their lvl and stuff.
