I'd like some tile that could kill enemy markets. Control the most markets and you're fairly certain to win. Obviously, you could be lucky with tower bricks and make a huge tower with 2x points, but ..
Starnge, I play it with a few other people and around once or twice a week and don't have this problem with the markets. True, we are all fairly competent players so are wise to the advantages that can be gained but it tends to be a very strategic game that we play.
