For example, I started playing ground because I was interested in tanks and enjoyed the gameplay. But I found myself frustrated by the mechanics (volumetric, ghost shells, later drones etc) as well as by the slow grind. Made it to 7.7 Britain and top tier Germany and Russia but I was completely sick of it and found I was angry way more than I was having fun.

I ended up trying air because I wanted to grind some cas for Russia and ended up really enjoying it. Learning Air rb was very difficult but felt very rewarding and outside of questionable balance decisions like all aspects at 9.7 I found there to be less bullshit in general. Also the grind felt way quicker. I now play air pretty much exclusively and every time I jump into ground to play around I get frustrated immediately.
