Staying in on a 4v15 isn't being good, it's being stupid. Ducking out after picking people off doesn't really make you a clown.
A major aspect to WPvP and just in general being good at the game involves knowing your limits and what you can get away with. If anything it's harder to go in on a large group and escape the fight without dying. Any derpface can zerg down a target or two and mash damage keys until they die.
