I would like to see new raids (G12 gear) (no challenges gear fair amounts etc.), more difficult so we need to bust our behinds to finish it. I understand that pit and aat can't be touched because of beginner players and casual guilds, but that doesn't mean we can't have more harder ones .
New LS and DS TB maps (just maps) no need to tweak anything. Just change planets and theme / chars.
Then, ship hardware and ship raid(s). "Coming soon" is way overdue.
Characters wise we need viable DS team in top arena (paper-rock-scissors concept) so please powerful Revan and Palpatine rework.
Then BH rework, and at least one new BH char (Jango, Hondo) in marquee - as they are required in DS TB. Probably leader with team synergy. Something better than what we have now.
Other reworks that I would like to see : Separatist, Droids, Jedi.
Imho game doesn't need 6* and 7* mods or lvl 90 yet.
Damn, i should have started this post with Dear Santa ...
