I would like to see a bit more variety added to the missions. 

I was pleased to see "Hot Pursuit" added just for this reason but how about a version where the target is opening warp gates or collecting relics. A summoning ritual which must be stopped inside a time limit, perhaps with the target(s) gaining power every couple of minutes you fail to stop it. A defence mission versus waves. A multiplayer "Last Stand" would appeal to a lot of players.

2.0 improved a lot of things but the current missions are somewhat unimaginative. The game has been successful at adding enough grind to keep us busy but i think it's time to add more entertaining mission types.
