Digging up this post because the devs said that the feat "Mark 50 enemies" will really have to be marking enemies in the next Conquests, not allies.
Which means, the last crate is now kinda gated behind a single character??? :/
I think that feats that require a specific faction like Jedi, Sith, non-attacker etc. are nice, since there are still many characters you can use to complete the feats. But "marking enemies" is an ability that only ONE character possess! I'm really not a fan of having a specific character required for a feat in Conquest...
(from what I've heard, the Death Mark doesn't count as a Mark)
Of course, it's especially frustrating for me because I specifically didn't want to farm Jedi Revan (I've never played KOTOR and don't care about those characters), but I don't understand in general why they would make a single character a requirement for a feat that's worth a lot of tickets (10 tickets I think)... :'(
