I like using the heavy flak because it’s fairly difficult to hit with at range, even though I know it is doing nothing that a half decent engineer can’t repair before I reload. I use it now for one reason only, lochnager achievements, and that’s it. I get bored sitting on my flak and wishing I could hit target like my counterpart on the lumberjack, but I don’t have the range. Lesmok rounds move so slowly, so you can imagine using charged or something similar. It’s like watching a rock fall off the wall, it starts heading for the ground as soon as it leaves the gun. On a positive note I do agree with the arming timer, its just like a round from the M 203 grenade launcher, it needs a certain distance, and rotation speed, before it arms itself. I can attest to that fact as we used to throw them like footballs at each other and never got one to explode. Ahh, the good old days.
