Why do I like the Trust NPC things so much? Watching that trailer makes me want to keep my subscription going just for them.... even though I do zero Adoulin content (have no group) I just muck around doing old stuff myself for fun at the moment lol.
There's only 1 character in Adoulin involved in the Trust system, those areas are far from a prerequisite.
I do absolutely love the kind of references made to past quests and missions during the Trust CSs - they're nice extra motivation to catch up on old content - it's kinda sad that some character's weren't given any for the sake of being login campaign rewards - particularly frustrating in the case of Mihli, who had the greatest quest CS out of all the Serpent Generals... actually, it's pretty weird that both her and Najelith were items while Zazarg and Galadar got CS... OMG, stealth female objectification, call Kotaku/Anita!
Anyway, it's also been neat they now reference each other in some cases when called in the same party - for example, I'd already summoned Galadar, so when I summoned Mihli she mentioned him.
On the topic of catching up with old content, it's interesting to see that sort of things that now count as Tutorial Records of Eminence quests - now it's AF aquisition stuff, which apparently were sort of endgame around the time Zilart was released...
I really should finish the ones I haven't yet...
