One of my guildies asked me to look at his pre-patch mare yesterday. He gets it out of the stable, I see it's 3 slots and has 700 INT. No resists set and 125 stam/dex. For round one he basically put everything into INT and HP. I've seen several 5 slot CU's with 125 stamina.
So glad I came here before I starting training anything or all my pets would be gimped too.
