@Bodack:
no, I meant that in one go 1 hour constant play on my phone makes my back hurt, not to mention, I don't think I have ever had a chance of actual 1 hour without wife wanting something.
on other hand, with new army built time will be around 12-20 minutes under new TB, I guess it will make it work.
keeping in mind, that during that training time, you can get chain scouted for 15 minutes, which wastes your TB.
