So for those that have successfully changed faction, how do things work.

1. Reputation - have they mapped it one to one to the opposite faction. PVP factions too.
2. Mounts - if you have a racial mount does it change to the new races mount. e.g wolves to elephants for horde to alliance shammies.
3. Achievements - have they mapped over achievements for pve. What about pvp achievements - That takes class for example.
4. Flightpoints - do you have to run round like a loon discovering them or do they give you them all.
