Yes a grenade on the top of the British tanks easily took them out. I’m hoping that in this game the armor on top of British tanks is weak like in real life.
If they had game modes that sort of balanced the lack of armor for Central Powers it could work. Like Allied Forces have two tanks but they have to follow them across no mans land to over take entrenched Germans. Then for conquest type game mode they’ll just have to sort of balance the two factions tank models, perhaps with captured Mark IV’s for Germans. Light tanks could be armored cars which both factions used to some extent and had at least a couple of models
Another note - from wikipedia
The extremely limited production of twenty (A7V) made a very minor contribution, and most of the tanks (about 50 in total) that were fielded in action by Germany in World War I were captured British Mark IV tanks (Beutepanzer). In contrast, the French had produced over 3,600 of their light Renault FT, the most numerous tank of World War I, and the British over 2,500 of their heavy Mark I to V* tanks.
They’ve said that different tanks will have different attributes and will be unique in their own ways. I expect not only different classes of tanks but that the touch pad may be used in a way to make vehicles, even within the same class, unique from one another.
As long as I can parachute out of my tank i’ll be happy
Maybe being able to catapult in the capsule and fly to enemy airship to capture it. Just like Bf 2142 
I like the sound of that. Hopefully i can fit my horse in the catapult capsule too
