Trust me when I say the only thing you need is being on the same realm in the same faction with everyone.
I've always preferred Horde, but if 7 months earlier we had to regroup as allies, I wouldn't have hesitated or complained one millisecond about it.
Faction change isn't available on Taiwan, and I highly doubt the ppl playing there would bother leveling again. Not mentioning the realm expats are actually on is pvp but not hardcore (7:3 ratio horde/allies), so we don't have the pvp/pve concerns we have on mainland.
When you log on a realm type "/join english
" to get in touch with the community members.
