True, that. There's an art to hiding behind the poles when there's a sniper across the way. May the best sniper win.
That strat doesn't work when you're playing with bots, though, because the bots can never get the flag. You can sit and snipe all you want, but you'll never score, because of those bots.
Edit: unfortunately Assault never works that way. The bots always end up winning it for me.
