It's slow, takes up a ridiculous amount of space, the battles are too short, and it takes forever to grind to higher tiers. There are a lot of issues with this app. I have nothing against Wargaming however, as their original pc app is incredible and much better. Here's a comparison - with signals and camouflage mounted on the pc, you earn ON AVERAGE about 1500 xp a game, with a good battle sometimes hitting 5000. This app, ON A GOOD BATTLE - about 500. Pc gameplay and graphics are better as well
