Mechanized strenght vs okw has nothing to do with any bugs, its all about wc51 and cav rifles synergy.
Easy8 is countered hard by panther, its slower than 75mm and has no chance to deflect shots while struggling to penetrate. You are hyping this combination so much but in reality its weaker than heavy cav (while requiring tons of fuel).
You know very well they wont fix any of the broken okw stuff. Command panther will stay, just as volks spam, jli and now even double schrek 250mp inf and call in tiger. Usf needs good stuff to counter this.
Cav on Dodge is all about cheese, or you succeed in wiping stuff fast early game or you end with 2 units that become more of a burden with time.
Panther counters Ez8, nothing wrong here. But Ez8 remains a good thread to Panther if picked out of cover and can defend itself in most situation that doesn't involve you having over extended. Ez8 is a good compromise to deal reasonable infantry damage and not being such an easy target for panther. OKW player is in the same situation here, he can't really go for Pz4 vs your Ez8 thus less AI potential.
