EOTS is the best of all the battlegrounds, a culmination of everything learned from previous battlegrounds.
WSG sucked because it was easy for a bunch of alliance tards to turtle. I quit playing it because I got sick of 2-0 games that took forever because the other team decided that if they couldn't win they would rather make the game go on forever. Turtling bases doesn't work in EOTS because the other team will score the flag over and over.
AB (previously the best BG IMO) felt cheap at times because it was easy to ninja a cap point and fuck things up. Claiming a cap-point in EOTS is a little more difficult, but not as bad as....
Alterac Valley, where you have to hold down a graveyard for like 5 minutes. EOTS is a symmetrical map as well, so there's no problems like with AV, where one side gets a cakewalk into the enemy base and the other side gets the Bridge of Death.
Even in slow, stalemate games one or both sides will probably be collecting resources constantly -- so there is always an end in sight. This is in sharp contrast to WSG and AV, which can continue on forever.....making casual play a dicey proposition. While it's theoretically possible for an EOTS game to go on forever, it's highly unlikely that you will spend more than 45 minutes in a single game.
