I have found that this is an issue aswell and especially in breakthrough with the repair stations being so close to the capture points and in areas with sightlines on Infantry paths so I'd propose that A: make repair stations destructable permanently B: up the damage of rpg and the prox mine C: max repair be 70% of initial health of tank D: on breakthrough game mode max 1 tank per side and only able to respon tank once a push
It took me 14 rockets and 2 mines to destroy one tank by my self no one helping also and the tank was completely holding down everything
But I do have another discussion on the breakthrough game mode in a thread so if you can go take a second to read it and let me know what you think
