I could be way wrong here but i don't think it drops anymore period.
The kit itself isn't bound so they get posted to the exchange quite often; i have three myself
I would like to see this and a tactical/engineering variant added as well, then into the reputation system. ESPECIALLY with the current trend of uber-awesome kits w/ five abilities being added into the 'outposts' system
But yes, you are right, Terradome was hardly popular before and it's even less so now.
The time invested in one single STF is frustrating, especially considering the others are much shorter by comparison now.
So I'm not surprised that if it drops there, it's not really being acquired.
I'm questioning the logic of moving a drop to an STF hardly anyone plays.
It's like they're trying to make you play it, knowing nobody really wants to!
Personally, I like the idea they kept the Borg Medical Kit dropping in Terrordrome. Not only it fits classic MMO dungeon crawling with a chance to get the rare drop by killing the boss mob, but the rarity of the kit dropping in that mission gives a reason to do it.
Otherwise they wouldn't have replaced the loot tables with Reputation Projects.
And nobody seriously does Terradome anyway.
EliteSTF has hardly any Terradome runs at all.
Whereas the other 8 STFS have plenty of runs.
That's a fair indication of how popular this STF is.
And besides, it's very predictable what will happen:
IF the kit should happen to drop, everyone will hit Need and the one player who genuinely needs it has an 80% chance of losing the kit to someone who is immediately going to run to Exchange and sell their prize.
Which might explain why nobody does it with a random group, they want to do it with friends who won't steal the kit.
