I completely get your point; I disagree how people seal club and light tank farm for WN8. In that concept I completely agree the metric is broken and complete bullshit.
However, I think this is where the miscommunication is coming from. I personally, only play tier 10. Feel free to check my stats; I rarely play tier 9 and I never stoop below tier 8(only when I started and would yolo rush in to die). Due to me playing only tier 10 it's harder for me to statpad as you'd expect others at tier 10 to be smarter at the game if you can see where I am coming from?
Due to this, I aim for 3.2k
