I would like to suggest the reputation rates for battlegrounds: Warsong Gulch, Arathi Basin, Alterac Valley(maybe?) get an increase to the reputation earned per battle.
At the current rate, people are reaching Grand Marshal / High Warlord before they get a chance to reach revered/exaulted with even one of these. I suggest a 10x increase, this would also allow some to supplement their standard pvp set with pvp faction rewards <3
Also, which is more a concern of mine, doing casual battlegrounds while leveling and get access to the rewards from friendly / honored would be a huge encouragement to have some casual fun in battlegrounds in between questing and leveling.
(And before someone states the obvious - Yes this is a PvE server, but battlegrounds have, and always will be, an active part of PvE servers)
To sum up - I suggest we increase the reputation gained from battlegrounds

10x would work fine I think
Best regards and warm wishes
