I believe they are letting your pets go between alts now, think i heard something about that happening soon when i quit.~ Also yes, vanity anything is worthless, a mount that lets you do what you already did is nothing, if it was faster then it would be worth it, but they arent anymore, everything is the same speed. An achievement saying you won something is... ok, but an achievement saying you did something in a raid, that didnt need to be done, it was just for the achievement, just means you wasted time.
