My opinion of what a great Borderlands 2 should be.

1) More Custimization - Such as character custimization that allows you to really have the ability to create your own character. This is seen in many games. Custimization is key. I'm suggesting something along the lines of the way APB( All Points Bulletin ) seen here : http://www.youtube.com/watch?v=2jOY2t2aHB0

2) Armor - Now I know in the game there are shields used, but I think that armor would add a whole new aspect on the game. Seen in Mass Effect & Mass Effect 2, armor can add on to the look of each players character, improving the custimization that much more. Not only would the armor be put in the game as a way to dress up your character a bit more, it should have attributes that could possible replace the use of shields. The armor should have stats just as the shield did; such as elemental resistance, elemental damage, health boost, health regen, ect. If this was added it would allow a player to mix and match individual pieces of armor to give them mutiple benifits that suit them. I think the armor should not get to out of hand though, just stick to a helmet, chest, legs, hands, boots, and shoulder.

3) Bigger Campaign - This really shouldn't need much explaining, I mean come on this campaign was pretty short compared to other games of its kind. I just think possibly adding more worlds to travel to, such as in Mass Effect, or adding tons of small dungeons all over the game, like in World of Warcraft or Fable.

4) Better Multiplayer - I think the 4 player co-op suited the game, but I personally got tired of just playing with only 3 other people. I would like to see something along the lines of a small MMO. Allowing players to roam around the game world and play in real time with other players. Also the party system should be kept, but allow you play with other players even with out partying up. Doing this will allow players to create a team or clan almost. One example of this that was very seccesful was seen in Phantasy Star Universe. It also allowed you to add players to a contact list in-game, allowing you to see where they are, what mission they are doing, what level they are, ect.
