Well done! With time you will learn to evaluate players based on the movement, positioning, shooting etc, almost like you had XVM. The big difference is, if you pay attention to these things, your situational awareness will improve, and you will tunnel vision less often.
Those are totally diffent tanks. The E-75, sidescrape=beast. you can also facehug excellently with it. Just watchthe turret face, some tier 10's can blast though it if you don't angle it.
the WZ-111 is pretty quick actually. If top tier aggressively push your flank, ufp is great if you can hide the lfp. More of a support role when in a t9 battle, but you turret will still easily bounce 9s. You should be fast enough to flex back if needed.
