I suppose I'd just want it to affect the leaderboard. Troop transport is good, and more important, don't get me wrong. Soldiers capture zones, not boxes. However, arsenal and medic crates, as well as armed vehicles, go a long way with speeding things up. Transporting cargo should affect the transporting leaderboard, particularly since many pilots lack the skill. I can draw up a rough point sketch when I get home.
I am unaware of the overhead it would have, but a custom support-call under the ~ menu would be an excellent communication tool for infantry, and could tie into cargo transport leaderboards.
On this subject, could we get the Taru transport removed from the lifter spawn? The other helos/Huron give plenty of transport capacity as is, even at server capacity, but the Troop cannot lift. Crashing helos for an appropriate respawn is cumbersome.
