why do WG hate UK?

Ectar:   wat?   I'd say once you play higher than tier VI you'll see the tanks are all quite capable.  The Action X tier X medium is one of the best mediums in game. The Fv215b tier X heavy is an excellent heavy with an amazing gun. The tier X tank destroyer - Fv215b (183) "Deathstar" has that fearsome nickname for a reason (and not because it's a 1 shot kill if you hit the exhaust port).  The Conqueror and Centurion 7/1 are both excellent tier XI tanks for the heavy and medium tree respectively. Again both tanks come with exceptional top guns.   Sherman Firefly, Cromwell, Cromwell B (Premium) Comet and Centurion are all capable and competitive mediums for their tiers.    As for the Conqueror Gun Carriage.... Well it's a bit like an orbital laser.   Lower tiers they're not outstanding but at higher tiers the British tanks are very well rounded.
