BE doesn't need one cuz it's bad accuracy and damage is what compensates for its armor
and the K2's horrible accuracy and low damage compensates for its 1.2 sec reload..
Black Eagle doesn't have good Armour, because tell me, what will a weak guy do with a full plate of Armour when he can't take much impact without collapsing? Having a lot of Armour doesn't mean you will survive with 600 health and having terrible maneuverability, damage and accuracy. Nearly all level 60+ tanks deal 200+ damage with HEAT to Black Eagle all the time. Planning on running? Good luck with the good traverse you have! Trying fighting? Good luck with that weak damage and accuracy! Trying to circle? Good luck trying to all East getting to the sides without dying!
K2 doesn't have 1.2 reload, it has 1.3, and what does having 1.3 reload help on when you can't score hits without HE or apps dealing low damage. It has terrible Armour, a straight 800 damage for K9 and 300 for Type 10. It's only good thing is the good health, reload and maneuverability, but what you going to do with it with no accuracy or Armour?
CaptainPrice, I don't want to get you mad but don't say things when you don't experience and feel tanks as I do on daily basis. I am not a pro on neither of the tanks to play insanely good, but they still need at least a cannon upgrade to make them balanced or at least suitable for level 67+.
