That’s your observation, but our wm survey indicates majority of WM forum community feels outnumbered half the time or less (Q8). Doesn’t seem so bad.
Your example is very extreme. You ever seen a 1000 of a single faction in one zone shard? 100 maybe, but that seems extreme too.
It’s already moving players depending on faction numbers in shard.
There are already single faction overflow shards.
Problem… how are you ever going to have ‘fair’ 50/50 faction balance within a zone shard. Example, 50 Horde and 50 Alliance are in a zone. 40 Alliance are at the Horde base ganking 10 Horde. 2 or 3 Horde are not afk, fight back, and feel very outnumbered. 40 Horde are spread in zone, the 10 Alliance out there feel terribly outnumbered. That is a 50/50 balanced zone shard, but the Horde and Alliance will still complain they are outnumbered.
Because with zone based faction balance, you will NEVER have fair balance. WPvP is not fair, it’s not designed to be. Like I said, if you want 50/50 fair WPvP, you’d need to balance it by subzone and a queue system. Yuck.
