If I was to fix world of tanks

I would first, add weak spots to the chieftains turret by adding a copula, as well as the making the gun mantle a weak spot, then, I would make the kranvagn have a 30 second reload, make its gun mantle a weak spot, make its cupola easier to hit, make the tornvagn have a upper turret weak spot, I would then nerf the lefh by making its gun have a lot less range around the map and give it a 12 second reload, I would make the matchmaker only allow for 3 td's, 2 light tanks, 5 medium tanks, 2 arty, and 3 heavy tanks, I would make it so only 5 premium tanks can be on each team per match, make the premium rounds have less pen and be more expensive, make standard rounds have more pen, remove stun but make splash have slightly more range, make the ebr get immobilized when only one wheel gets taken out, so its similar to tracked tanks, make the 279es hull stronger, but make the cupola bigger, remove plus 2 minus 2, and make it plus 1 minus 1, give out more 3d styles than tanks as rewards, but make them alot easier to get, thats about all I got for the game so far, any ideas, any thing to you would add or change to what I would do, write a comment to let me see your ideas!
