ohhh for real eh? i have been using zerg and doing roach rush all the way to #1 i had no idea it had anything to do with build orders. i have been experimenting with 14 pool 16 hatch now and its actaully beeen working pretty good. but I just do not play against terran, i just cheese off the bat because they have too much of an advantage over zerg
naw hes totally wrong, the game doesnt track what race you play or what build you use it comes down to your matchmaking rating
lets say you are in gold league, if you play against a silver leaguer and lose your mmr will tank, if you play against a platium leaguer and win your mmr will skyrocket. if you win a bunch of games in a row and your mmr goes up to that of a league above you, you will be promoted. if you split games in your league bonus pool will continue to feed you higher ratings but your mmr will still be too low to get bumped up
basically as long as you lose to people in your league you wont get promoted, if you notice you are getting more/less points off of wins it is because you are playing against people with higher/lower ratings than you. if your win ratio is 50% in bronze league the game is gonna leave you there because it thinks you are being matched properly, if you go on a huge winstreak you will be bumped up
oh and the best way to just rape through all the leagues is to cheese it
