I got to thinking the other day about the next expansion of WoW and I started to think that it's going to take a while to level an alt. So I figured that what if Blizzard implemented a system that would give you 10% more xp gain for each max level character that you have, capping at 50%. So in theory with enough BoA's to get you to 50% extra already, you could essentially get double xp for everything. Let me know your thoughts. Max cap is still at 300% with RAF, so if you are doing RAF with someone you don't out level them.
I do enjoy the content when leveling but doing over and over is boring unless you swap factions, but then it still gets boring.
Let me know what you guys think.
