I still play regular but it is getting pretty mundane. But that is not because pokevision and other 3rd party was banned. In fact they were supposed to be banned a lot earlier. The map users (myself included) will never pay for pokemongo but might pay for the map. This is not a good business model for them and in fact it defeats the purpose. Instead of hunting or seeking you are basically shopping.

The reason why it is getting boring is actually something else... it is in the flaw of their game design. This game is extremely biased toward people who live around water with high density such as Santa Monica and San Francisco. You can catch Dragonite and bunch of starters there. But most people instead will catch eevee and growlithe at the best. Basically after a while you finish catching every pokemon around you and there is nothing else to do other than fight gyms. But gyms are so easy to beat that you don't have much incentive to defend it.
