There needs to be a *reason* to use touring events. Higher worker stat gains, significantly lower injury rates, normal event spam gets penalties, high pop gain in lesser known areas, etc, etc. As it is there is no reason whatsoever to use touring other then "realism" that you can easily get by just using smaller events in smaller venues.
If you use touring you don't make money and you don't gain popularity. They're shows that do absolutely nothing for you as a promotion and are essentially just shows for the sake of doing shows. They are pointless shows that if they didn't exist would do nothing for or against you. The only reason you might gain pop is televised tour shows but you can just as easily do televised regular shows and reap all the other benefits.
