During last 3 days I've won 20+ and only lost 1 wsg queing as warrior,mage (duo). We are both horde.
Overall I have 70% win rate at wsg:
Do they need to buff Alliance racials? Does ally need more healers/tanks?
On a more serious note, this thread was directed to those who regularely post that the other faction is better at battlegrounds than their own faction. It's not the faction that determines the winner. It's everyones contribution. Others contribute more while others contribute less. Take what ingredients you have and try to make the best cake out of it. Don't complain about your teamates. Make the most you can out of them. I specifically remember one game last night that 9/10 alliance were a premade from a French realm. Before the bg starts there was a couple of people complaining "let them win" "don't ress in the graveyard so it ends fast" which changed their motto after we went 2-0 up to "those french really need to learn to play" "worst premade ever". Eventually we won 3-0 and they didn't even give up. They were strugglying to the very last minute.
Finally I remember a game where we were losing 0-1 and alliance was camping our graveyard. They had better gear and they were zerging. I thought our only chance is to MAKE alliance leave the graveyard. How to do that? Take their flag and kill their (solo) flag carrier (at their territory), proceeding to cap. That strategy worked. Allys were forced to abandon graveyeard to return their flag. That make it possible for the camped horde players to breath and play. Eventually we came back 1-1 before the timer run out. It was a case of a certain defeat that turned out as a victory. Alliance zerging before was forced to be split into lesser numbers.
