Ya i play both british med and heavy line.
The BlackPrince really a good damm tank.  If yoi know this tank which angle to pit....even IS-3 also can't dmg you....

I more play as flanker & active scout for most of the MT line as it have the speed to run away and good enough pen to fully utilize the rof on to put hole on most heavies of their tier. Centurion on the other hand have to play as support/ sniper role as it don't have the speed and relatively large like a heavy tank, quite maneuverable tho.

Matilda?

This tank easy to play. Mount the 2pdr X-B, stand back and snipe. 

If you're top tier, you can play it like a KV-1 and charge. Mind the SPGs though.

If you're mid tier, act as a support and sniping tank. If you see a HT being busy with another, go around and machinegun his arse.

As bottom tier, same as mid tier, except you probably should find cover and hug friendly heavies where possible.

at low tier, do not expect some high accuracy, when u get last gun of Churchill1, u can feel the power

Because is sea server......

Always full of surprise, crap, lemming , coward, noobs.
