Yes, most paws I've seen on live is 5, most 1 or 2 in the course of the play through. Had to spend on hammers just to get the one or two down on multiple boards.
On the one with 5 I ended up spending for extra turns several times because more paws kept showing up.
The game seems to have been tweaked a lot between beta and live, but I'll reserve judgment on live until it is about done since I am getting a lot of daily specials, just not sure how that is going to translate into getting a second main event building.
