Rocket artillery is a cool feature - but completely useless. It is supposed to be anti-tank, but even when you aim it perfectly at a tank, it is not a guaranteed kill. Or the tank just drives away. OR. building is blocking it. Also when the tank is in the battlezone, AT soldiers simply kill the tank before artillery arrives.
So here the suggestion:
Remove the gray zone blocking rocket artillery
Gray zone tanks are often in the open as they have better view for kills, but have barely any danger of AT soldiers or explosion packs and therefore get dozens of kills. Rocket artillery could be the perfect counter - these campers put less attention to the map, not seing the red artillery circle and also since they stand in the open, no buildings are blocking the way.
I agree, recently I started using event radio squad in br 1, and it feels so good to blow t28s with rocket spam. but its not a guarantee hit, they either moves away, or dies way before rockets launched, not the mention damage against infantry is joke. so I fully support the removing greyzone blocking, this feature would be better if its for the greyzone campers.
