It strikes me as odd to think that I'll have Battlemaster on characters that have literally never even set foot inside a BG. Not really offended or anything that it will work that way. Just an oddity.
I admit I am kind of bummed that I've erased some of my old vanilla characters a long time ago. Some of them had quite a few HKs that would have been nice to add to my collective total. No real harm done, though.
