-The ability to organize and control bases, operations and missions to squad members or misc npc's that the main character can send out similar to assassins creed blackflag, but instead of just sending them out and being done, The main player can actual choose to join in on these side tasks and assist either the squadmate or a significant npc before or during a live assignment.
-EXAMPLES: Sending a squadmate out either alone or as squad captain of misc Npcs or other team squadmates to complete specific objectives, securing a base, eliminating a target, Deliverying something important, etc. Being an explorer and battle hardened veteran and having nothing of significance to do at the moment, you have the option of actually joining either said team (instead of waiting for some dumb timer) before or during they're assignment either as a part of the squad as a foot soldier vanguard, supervising from orbit or nearby viewing the entire fight from they're 1st person camera perspectives or actively engaging enemy from a distance.
-Bringing a variety of body,armor and weapons like in mass effect 1 but better. I felt suffocated when I couldnt customize my weapons and armor the way I wanted to in mass effect 2. Mass effect 3 did a little better but it still felt like somethings were missing like alot more piece by piece armor, weapon and body modifications.
-Being able to view inside of the mako and interact with squadmates and or the tech inside.
-Being able to establish personal bases through out the galaxy wherever just because we fucking can.
-Communication,Communication,Communication!. It would be very nice to be able to have some form of communication, Specifically after the main story is done to complete things that I didnt during the main story. I hate playing a really amazing RPG game with characters that seem to "die" after the main story.
Just to name a few, when I think of more thing which have but cant think straight right now, I will post it.
