1) Level cap increase to at least Level 75. 2) Smarter enemies and a more diversity of them (i.e. no remakes of enemies and giving them different names). 3) A new vehicle, preferably a flying one. 4) Bosses with smarter AI, especially those that can adjust to the player's tactics. 5) Currency that can be used in normal game.
1) Level 60, that should be enough. 2) A new spartan laser type weapon like Halo 4. Add all new challenges for the weapon, and give it some oranges to give us something to hunt. 3) Mr. Torgue sidequests, 3 at the minimum. 4) At least 3 different types of enemies. Bring back the aliens from Borderlands. 5) Forest-type area. I want to explore a dense forest.
