The biggest reason is the widespread mindset problems though, not the way the horde plays. So even if Horde would play like the Russians, it still wouldn’t have a big impact on queue times.
The only real way to solve it is to remove solo queue. No need for automatic matchmaking for xrealm teammates in this ranking system anyway. Alliance can only win as full premades, because the mindset goes to hell otherwise.
It fixes most problems in PvP, you know? It’s just that the entitled solo casual whiners wants everything handed to them in LFR-level of difficulty.
