IMO molecule is way op. Even I'm unstoppable with it and most of the good players on the server will tell you I'm average at best.

Shadow Hunter is the only real counter for it and since nobody went SH I was basically untouched. Also, 3-4 of my deaths that map were from before I even went molecule. If lace allowed you to shoot through the invul like it does with SH invul it would be more in line with the rest of the races but as it stands now... yeah.
