Sorry guys! But they're not going to be put back... Reasons are listed below :X
I. They won't be coming back any time soon.
II. We run on an Aegis server, the new patches for Aegis haven't come out yet to fix the problem.
A. If asb were to release the latest one, heat would be disabled and you wouldn't be able to stack heat and kill skegs.
Addendum: Heat once again, was never meant to do this. It was always a glitch and the skegs have something in the code which causes the crashes. It is not possible for us to alter the skeg code as Aegis will not allow for us to do so.
So no. They are not coming back. If and when they do, by that time, heat will be disabled and SG's glitch will be fixed. IE: 1 Heat / Jumping doesn't trap / only way you use heat to hit the enemy is to do running / walking into them.
