1st or 2nd ed

By Gatha, in Chaos in the Old World

I was looking at finally getting the game then saw there was a second edition out. From what I could find, all the 2nd adds is more card art, fixed Slanesh, and has a problematic board. I imagine the board issue will be fixed soon, but is there any other reason to get the 2nd (i.e sturdier cultists)?
