Here is a replay that applies. BUT (sigh...) please ignore my stupidity in standing under arty fire lol.
1. I went full tank spam and he went full arty -> he lost horribly in initial engagement and every time after that.
2. South rock arty dropped my base and I succeeded in killing all arty with only 3 tanks and good intel. I lost a good bit of pgen, but not anything to cry over and still came out on top.
I think this is a showcase of how arty loses vs tanks and intel/countering. Arty does not need a nerf.
