Hello Kuzmin
A 100% boost may affect the system and items balance. With a greater upgrade boost many high grade items may lose it's value. And of course this will affect the in-game economy even more.
Take into account that before a boost is applied we must evaluate these factors first.
We are sorry that you are not pleased with our service at the moment.
Note that we are working everyday to make the game better.
If you have any other concerns, just reply back.
