Agreed and there should be no cap on floors or at least as far as us players can tell. The higher you go the harder it gets, but at some point it gets too hard even for the best players creating the illusion that it just keeps on going and only by reaching say level 80 can you go higher which would be only by next expansion. Would add an interesting challenge of how high can you go? They can then just up the level of the floor you can start on each expansion so you don't have to go through so many of the lower floors.
