I am a trooper, and my gun shoots bullets, but for some reason I log in now and when i shoot, my bar for how much spells u can cast turns blue, and drains 3 and I shoot grenades instead of normal bullets...
It's really annoying lol, does anyone else have this problem? or know how to fix it?

Probably moved the wrong talent over to that first slot.

ye maybe as Caedus says lock the skills on the left side on the bar down there and u cant move them

Yep I had this problem on my agent. Using the standard attack always put my guy into cover instead of attacking.

ya you might have deleted your first skill or somthin would happen to me all the time then i found a lock button lol
