I queued up once after The Vault ( the mission, not the event I never even seen anyway). I did a lot of non mission stuff in a starbase in between. So I completely forgot I was still in that shuttle.
I would have been glad for this feature then, but can see how it is annoying when you make a deliberate team decision on using small craft for this.
People don't need a Low Tier ship to grief they can just AFK and be useless in a Tier 5 ship.
There is no way to get rid of somebody intent on ruining it. They can always find a way. The General Consensus is that a kick option will be abused.
WoW made it so you can't kick during a loot roll, which seemed to work.
Although I was sure you could take Shuttles into a private match.
I'd much rather have a lower-tier ship, that's well kitted out, flown by a player who knows what they're doing than a rainbow boat T5 player who, as per the 'Worst STF' thread, thinks that they're awesome (and will say so) but has no idea.
