So, the only smart thing Horde players have come up with is we let Ally win WG for a few reasons.
First: The losing team gets stacks of tenacity for each loss making it easier when we actually want to win while we're doing the following step.
Second: So we can farm Ally, however most Horde "WPVP" brainlets unfortunately need to either vastly outnumber their enemies by either purchasing the help of Horde multiboxers or making their own multiboxers, since they lack a lot of skill and class knowledge. I even think I saw a Horde multiboxer get pulled off the roof of VoA earlier today and all his toons fell with them and died, soooo yeah, case in point.
A lot of great players are unfortunately in Arena or BGs, and are already BiS so they don't need WG. You can tell the plethora of garbage MBoxers from the very very few good ones. (Ltyrantjr being literally the only good Horde MBoxer).
Lastly: Expect more and more Horde Multiboxers, fresh 25 mans are being created quite often and are actively sought after since we can't rely on buying the help of the big Mboxers anymore. Although quantity doesn't equal quality, unfortunately this is a game with health bars and 25 characters can nuke an HP bar faster than 1. So they farm WG fights and lose so they can farm the Ally come to get WG stuff.
This is the new meta, enjoy the time your character is alive for now unless MBoxing is out right banned, which will never happen because [REDACTED].
I detest being Horde, but unfortunately the racials are better for PVE, so I just bring out my popcorn whenever I see people complaining about various Ally guilds in the in game chat channels and requiring the help of mboxers because they can't match them in skill.
