I had aquired the teleport pyramids and love em
but then for no reason they disapeared from my inventory around the beginning of act 4! and I ain't about to go back and remedy this (2 days of play? not thanks) there should be some sort of if statement to check to see wether all the pyramids are in your inventory when you leave the battle fields or not since I think thats where I lost them, if it isn't then it would still be nice to somehow aquire them in the after game battle fields if you havn't!! they are super helpfull!
that's number one
number 2 is the LACK of gold that the merchants have! I have items (magical armour and weapons) that I can't even sell! >_< and running back and forth between randomly generated battle fields takes about 5 minutes on my computer -_-.
