I'd really want to see the species from Star wars galaxies. Mon cal, Rodian, Wookie andrando( can't speak basic so probably wouldn't happen. Also would love to see the Barabel and Nautolan species in game. Barabel being my personal favorite.
I understand you wanting to keep servers full of people. But i don't want to pay and have to wait every time i want to play, If my one person or my entire raid gets dc'd, raid is over. There should never be a Q to get in the game.
