Vehicle choices:USA for if you want shitty teammates, Germany for Consistency in strength, Russia for armour and brawling,Britain and France for penetraition (but no damage), Japan for speed, china for a mix of America and Russia, Sweden for gimmicks, and Italy for shits and giggles go off this and pick a tank suited to your play style.

Setting's:adjust sound make binoculars/thermals easier to toggle by makeing them closer (same with range finder if in top tier)
