So far all higher tier UK tanks are pretty sucky imo. On the other hand, the low tier ones are complete rape ! A13Mk1 armed with the BESA Gun is just insane, most probably the most OP tank every created. Even more OP than Tetrach on Tier 2. Also Matilda and Valentine with the squeeze bore guns are great for sniping higher tier tanks, plus they have some pretty though armor. Crusader is pretty cool too, very nimble and agile tank, gun is kinda random thou. Doenst want to pen T5 heavys somehow ..
