More.
Garrus, Thane, Legion, Wrex, Tali, Liara, Samara and Mordin return, preferably as usable squadmates.
Reworking of combat powers, so that they actually become useful again:
Barrier resists bullets and tech powers, strongly damaged by Biotic powers, but dampen any Biotic effects (I.E: Throw just knocks them off balance, like 5-10% of it's usual strength sort of thing).
Armour resists regular bullets and is highly resistant to direct Biotic damage, however is fully affected by Biotic physics attacks. Reave/Warp do minor degenerative damage, but make the armour far more susceptible to bullets. Tech powers do 75% or so damage against armour.
Shields resist against bullets and biotics equally, but half of what armour does due to the ability to regenerate. Tech powers do full damage against shields, or bypass them completely.
More armour variation and customisation.
More weapons, and the ability to modify the weapons with different pieces, each type of weapon having a large number of modifications to allow customisation of play style. This would be in addition to universal tech upgrades.
More in-depth RPG elements, like Mass Effect 1. Larger skill trees, unique events give unique bonuses, hidden/side quests allow improvements to existing powers/abilities, etc.
More freedom. I want to experience the galaxy of Mass Effect, not just small areas of the Citadel, Illium, etc.
Better quests. ME2's quests were rather tame. Overlord and Shadow Broker DLCs were far better than any of the quests in ME2. More like that!
A Yahg squadmate. Perhaps it could be balanced so that it couldn't take cover, and when under 25% health it could rampage and target you as well.
Far more in-depth worlds.
More exploration tasks.
Probably some other stuff too.
