A better solution would've been to have a mix of HD 2.0 and HD 3.0 worlds. You would retain all the current customers that wanted to stay in 2.0 and make the other customers happy with 3.0 that wanted this change for one reason or another.
Next market the product better so you can fill the worlds. Users come and go, but there has been little or no effort to market the product.
As of a result of 3.0, we are losing coaches and some of the coaches that are planning on staying are reducing the number of teams. Part of the reason being, the amount of time it's taking to put in scouting and recruiting effort. Because of this, there is talk(not necessarily by seble), but of closing down a couple of worlds, which will **** off more customers. Doesn't sound like a great way to run a business if you ask me.
