Paris and Minsk.
If there is one thing WG has done over the years to piss me off the most it isn't arty, lack of weakspots, the abuse of light tanks, or EBRs. It's been map design and has been the most depressing thing about playing light tanks. Let's take Kharkov for example. As a light tank I have 2 options when the game starts either go 1 line and brawl with mediums dodging arty fire all the while or (if there are no wheelie bois) go middle and sit in a bush in F4 or E4 spotting maybe 2 TDs who probably won't get shot. That's it and its fucking boring.
