thanks for the stuff to think about guys, I was aware of the battle pet issue but the accounts I moved haven't even been active since battle pets came out so I'm not concerned about that.

the single authenticator is definitely the reason I made this change. My first two bnet accounts used to be covered under the same mobile authenticator and sort of grandfathered in after that was banned, but this summer the forced authenticator reset meant that I had to choose and bump one, which got hacked within a few days of being reactivated (not a huge pain, I was playing at the time so they only had about 8 minutes on my account, enough time to vendor strip one toon, it was easily restored) which is when I decided I needed to merge down. The best part is going to be spectral tiger x5.

I didn't have instant mail before for all my toons because 1/3rd of them are in a real guild and the rest in my (level 5 now) bank guild.
