Updates are brutal

I understand that updates are meant to enhance the gaming experience, but the last couple of updates have caused some undesirable gaming glitches. I have noticed more and more network lags due to the shear size of participants. I have lost far too many battles due to this and its getting old. It also seems like my win percentage only moves when i lose. I have won 5 or more games in a row and my percentage only moves up 1% and losing 1 game moves it down 1%. Seriously! Now i have larger tier tanks having the ability of shooting me through solid buildings. I cant even run through the building ,but they can shoot me. Thats just wrong. One last thing, i hate that i cannot shoot at a tank from a distance without being seen (light bulb appears) but they can sneek up right behind me without any indicator they are there. What ever happened to the a tank automatically being seen when a certain distance from the opposite tank?
