Blizzard can stop ignoring the cave as soon as they make the Alliance base as hard to defend as the Horde one. Alliance should always win in AV, literally all you need is a few hunters defending.
Horde got more choke points where Alliance has to throttle through, ontop of that Horde has 3 buildings where they literally sit ontop of, making it hard for melee to even touch any horde sitting on roofs, gates or towers. You say alliance base is easy to defend, yet horde just runs through without much opposition.
Also the turn in dudes are also always dead on alliance after first push, especially the armor turn, which Alliance cannot really defend.
IBGY choke - WFWT/EFWT choke - even the opening gate to the actual village is a choke.
Hunters make all of these a living hell, bridge, due to its size is a breeze.
dude that choke is smaller than the bridge, literal troll. the GY is not helping for alliance ontop of it.
Horde can delay alliance right at Balinda, then at IBGY, the first gate of frostwolf village, then at the twin towers.
Alliance can delay at Icewing Bunker, up to the 2nd to last GY and Bridge.
It’s not a lie, also taking a bloody map screenshot when actually being there it is a whole different story is just twisting the facts. Play the BG or shut it and stay to retail clueless.
