Yes Imperial the buggy mission is the one you have to free the shackled leaders. Seems like only 1 outta 5/6 work right now, everyone wants to solo camp it rather than group and get it done, so thus everyone fighting over 1 single spawn.
Much like the Marksmen for the Airstrike Codes (drop rate sux, spawn rate and number of spawns sux for such a small confined space and large populace of players wanting to complete it).
I'm no imperial. I didn't understand ANY of that.
