What i am currently thinking of is they also should add a feature (beyond just making your partner's dialog easier to read) where, whenever you have to make a choice in a quest/whatever-E.G, whether you want to kill the two legionnaire at the bridge at the very beginning of the game- you would have the option to 'call' the other main player, and he could chose to warp to you via the teleporter pyramids and participate in the dialog.
