I should be the one Facepalming, I'm asking for people's opinions. I already read the wiki and I know the abilitys.
For example F seems good for a MS that has no skills yet, but after leveled up, useless unless you choose another MS that has no skills.
Then D is good for MS that already have skills, but aren't leveled up completely, even if they are still get a 20% bonus to points.
And A always gives you 30% more points which is good almost all time but not very good if the chosen MS is not leveled.
I know they pretty much could cover each others weakness if I had them all, but I'm asking for a "Overall" Operator.
