Seriously, why does everyone want to fight out in the open when they're 10ft away from one of their friendly turrets? I can't tell you how many times the bottom player on our team will meet the opposing player halfway, start losing, and just bum rush and die. Then of course the opposing player starts capping our bottom. You can retreat you know.
Also, what is it about Dominion that turns everyone into an melee expert? I can't tell you how many times I see a Soraka, Janna, or Zilean decide to fight it out against a Jax or Gangplank in hand to hand combat out in the open, instead of backing off, heading to a turret or close teammates.
I understand you have to be aggressive in Dominion, but there's a line between aggressive and dumb that some people don't seem to get.
