PvC (Player vs Computer)
Just like PvP but versus computer instead. Can be played offline too. Perfect for any new players to practice for real PvP against other players and home their skills/builds and combos and without the abuse too.
You could pick your character from your list, then pick an opponent (a range of opponents, each vary in builds and levels) Also pick a difficulty level, number of rounds etc and away you go!
If its been suggested before no problem, I doubt it'll happen anyway, but I'm just putting it out there just in case :-)
