first off thanks, and second, i just thought that maybe if i was playing as a light guy maybe an operative? that i would want to get across the battlefield quickly.
So my idea was maybe map a button for it or something? i dont know but i figured it might be useful for guys that may want to avoid the main conflict in the middle
For as far we know, the option to put your gun away isn't there, so it would be impossible to map a button for it.
If you want speed, Light will be indeed the way to go. I don't think Lights should engage in any main battle, except to support their team or surprise the other one. Lights are probably more for one v one, flanking and rushing to certain objectives.
You can play any class with any bodytype and vice versa, you don't NEED to go operative if you're light, nor do you NEED to be a light if you are playing as a light. You can choose freely.
