i wish they did that much DPS to building and walls, but sadly the listed DPS is all they have. also they only attack buildings and wall, and never attack defenders or generals.
i do think they do that alpha damage thing that you talked about with tanks in a previous thread, so they might fire once every 3 seconds, and each shot is 1,476 damage.
I think that's the only dps considering it is not efficient vs defenders. But it kinda hurts my tanks when cannon is on defence. Since the arta shoots probably 1 time per 3-4 seconds? It lands quite a huge dps at one time. So 6 could be a waste of dps. Also korean gunmen could make its advantage marginal. Also may need a buff on dps
that's why i like to run 4 cannons, 2 supply trucks, 50 Blackwatch, with 2 sappers, 2 raiders, 2 HC. i know it's not the most effective army for max loot, but it does have a chance at 5 stars, and that's what i like trying to get.
