Wow, that's cool, an adult person with job and kids. So you are a lucky man. you can play if you have time, or not if you don't have the time.
But you can't let play your bot because you haven't enough time. how should this work? your bot level you up, and when you have time to play(christmas holidays or sth.) you'll loose all the time, there wasn't time for you learning the geame-mechanics because your bot played.
You get that problem?
And it's wrong people think there are just on Hightier some good vehicles... that's so wrong, believe me, funniest vehicles are spread through the whole game, same thing in WOT. There is no need to bot, you just cheat yourself and loose when you handplay.
With botting in WOT/WT there is no room to increase the learning curve, and when your bot reach hightier, it will be much more difficult for you to rock then it was with the lowtier "shit vehicles".
