Don’t waste your time installing this

Tank turns only in 20 degree increments, you cannot turn smoothly.
When using sniper mode and you have an enemy tank in view and this tank hides behind a rock or another obstacle, sniper mode automatically zooms out, which means you lose valuable time when the enemy tank shows up again.
Default controls with left-shift for sniper mode isn’t very useful. It would be better to use right-click for that.
News - is a completely useless feature, looks more like a spam email. I didn’t even read it. It’s too much stuff and does not seem to be relevant. Just something about getting points or perhaps suggestions for purchases. It’s just too much stuff to go through to even understand if it is some in-app purchase offer or some goals in the game. Not sure if I have to go through all these messages and complete some mission objectives or if it is just spam.
Too many items to upgrade, I’m not sure where to start and where it ends.

If you really want to have fun in tank battles, try Battle Supremacy, it has only a few in-app purchases, if you really want some extra stuff. World of Tanks Blitz seems to be designed to purchase coins and consume them.
