1) More conversations with ur squad mates on the tempest
2) The option to actually talk to squad mates on planets would be cool, to get there opinions on the current mission obj
3) More multi-player maps
4) Upgrades to the Nomad, like a machine gun upgrade with augmentation options would be awesome!
5) Lets bring the Quarians to the party with the option to visit there ark and romance options if possible
6) General bug fixes
7) Upgrade options for your colony's like expanding with extra buildings, different types of buildings, Bars and coffee shops, entertainment options, apartments, wall structures and defense options, etc. This can also give you cryo pod points to spend and awaken more peeps to fill these expansions. To be honest tho, i did think we would be able to do this anyways. Anyways, please Bioware consider this as it would add an important aspect to the game.
8) More gear
9) I agree about the option to be able to change the power buttons in multi-player.
These would make the game more awesome than it already is, i hope the next patch is soon.
