My weakness is with my swallowing/speaking. I have very minor ptsosis on the left side that does get noticeable when I try to force my eyes in one place for an extended period of time... but I've always had that. I have minor limb issues but I really think that's mostly due to atrophy rather than MG. chicken wing test didn't show any weakness, but upper arms held to your side, forearms straight out in front of you and don't let the doctor push them open did show some fatiguing. It is a really small muscle that controls the arm in that position/movement that I didn't really build up before I had to stop the gym.
