I think everyone does that at the start. The problem is when you die 3-4 times from the same teammate and when you look at the scoreboard he's rank 27, so he's been around for a long time and should have learned by now how to play properly.
I'm thinking of buying Dishonored, just not 100% ready to pull the trigger. The problem being that I need to decide tonight if I want it or not as the deal will end by the time I get on Steam tomorrow. Decisions decisions...
Did you play Dishonored before??? I really didnt like it and returned it after 1 day. I hate games where you have to use skills that change the graphics completely in order to see the enemies and that becomes 90% of the gameplay.
