from a pvp point of view, it will be cool if warmane could implement a short period of changing faction from alliance to horde freely
actually after many many alterac i can feel the ongoing horde/alliance dynamic
alliance have more powerful healers and paladin buff and freedom give serious edge
as i play both side through mercenary mode, i saw horde more desorganized in term of healing while they are smarter strategically, they managed to get bridge each time ninjaing snowfall and resist alliance push thanks to many mboxers on horde side.
if you remove mboxers you can feel the unbalance immediatly
i like the challenge to confront strongest team/faction so i will change faction surely
we have to remember that the global player base is not the pvp player base on the realm. You see the pvp names coming back again and again on the battleground while you never see some names who do only pve.
Sometimes i wonder if it can be wise to open faction change to those with certain amount of hk. For the example, let's say all players above from R6-R8 can change faction for some days if they want it could be very balancing for the pvp community on Onyxia.
thus, you don't touch the whole player base so much.
but it's possible to have reason for pve boy to change faction and maybe some rule like changin faction could be implemented
