Blizzard has discounted faction changes and character transfers by 25% for the next week. This means that you'll be able to get the services for the following prices:
- Character Transfer -- $18.75
- Faction Change -- $22.50
This is a great opportunity to transfer characters and get a new faction started before Warlords
releases on November 13th. Interestingly, this makes the faction change cheaper than the race change, which is still going for $25. I gather moving from a human to an orc is easier than moving from a human to a night elf, at least for the next week.
A discount of similar stature is running on the EU servers. The sale ends at 11:59 p.m. PDT on Wednesday, October 29th, 2014.
