When 1 mistake can make or break a game, some bad mannered moves are still in the unknown zone for the high rated premade scene.
1. Stealth caps: where the user stays in stealth throughout the entire cap
2. Standing inside the flag: you are not able to see any nameplates from both sides of the flag
3. Melee unhitable: In alliance warsong flagroom there is a spot that makes you unhitable from melee attacks spells does hit him. http://i.imgur.com/Oh9rDgY.jpg?1 sorry xhaibara didn't wanna call out names but well you use it quite often so it was bound to happen right.
So these three abuses is being used quite often (mostly the same persons), dont know to much about the second one but the other 2 is known.
