I was going to say "the best way to win is to not fight at all". That is, to even avoid having to compete with a Goliath.
Then, I remembered how Runescape became the 2nd most popular MMORPG with 6 million players (1 million of them paying), even though it is inferior in just about every way to WoW. I have no idea why 1 million people would choose to pay to play Runescape over WoW. It isn't even very much cheaper.
