Its not the sky, it the fact that the M203 ATM has a very very short fuse. I CANNOT shoot from A to the bridge on Sinjar, and that really bothers me. Even if I arc it right, blows up before it gets there. That, and the lack of leaf sights for the 203 is really disappointing.
Its an incredibly welcome edition to INS, been waiting for it for it since launch. Great fun to use already, just needs some tweaking to make it more formidable.
