Would you care to elaborate more? Are you talking about the "skill" it takes to shoot over terrain? Because if so, even at the highest level the randomness involved mitigates the influence of skill. If I have to time my shots in between bumps, and there's still a 50% (or so) chance of the tank bobbing up/down the moment I fire, then skill isn't a huge benefit in these cases. What do you think of third person shooting?
