I can tell you from experience those "Vetted" Piv's lose to the easy 8. Every time. Even if you flank, even if he sits still and lets one of them fire at his rear the entire battle. Even with armored skirts on both. Easy 8 wins.
On the easy 8 itself, i actually think its fine as far as power goes, but it need a price increase. 380/145 at minimum. It's just too good an all around tank to be at such a price.
Show me a video of 1 E 8 killing 2 skirted vetted P IV's...
The video either doesnt exist, or the OKW player has some of the shittiest microing skills ever.
No way an E 8 will win a fight when being attacked in the rear, 2 good rear shots and its already on fire.
