Add to the list...Obsolete tanks in Today's Meta. I'll start.

Einzelganger7: Hmm... for me maybe the German light tank branch, I like most of the German tech tree branches but the light tanks from tier 6 and higher are terrible, the main solution is really simple, better shell velocity and maybe increasing alpha on the HWK 12 to 280, RU to 320, and Rheinmetall Panzerwagen to 360-390.
