I really REALLY enjoyed the pacing in the endgame invasion mission but I was extremely annoyed at the glitch that kept happening to my character spawning into the mission with zero ammo for my specialized weapon...was planning on trying all 3 specializations but due to the fact that it kept loading me into the mission with zero ammo for the special weapon made me give up after playing thru one entire time and NEVER getting ANY ammo for my grenade launcher I mean what's the point of allowing us to try out the specializations if your not gonna give us ammo for it to try the weapon...please fix before launch or I will be very disappointed
