They really need to sort out the chaffee's MM by limiting it to tier X not XII games or at least fix its acceleration, there are times when I'm in a top tier game where I seem to get spotted even before I've even laid eyes on anyone and often (especially on the more open maps) I get straight up one shot killed by someone outside my view range even while traveling at full tilt or especially when climbing hills.
It also has no chance against high tier lights and I'm often mauled by likes of the french AMX's and T71 who are just as quick, better armored and sport autoloaders.
It only really shines on urban maps as its high turn rate can help you dodge between buildings pretty easily but its high climb rate really causes it to struggle on any open maps especially now that it cant reverse at top speed like before 8.0 hit.
