Re: How do you have your tanks set up?
Panzer 4 and the Valentine are in different teams, you don't have to choose between them. But among tanks they are my favorites for their factions. Relatively fast and acceptable armor.
They are about the same, I run different specs on them. The upgraded cannon is nice to have on both.
I like the mine clearing mini-rockets on the Valentine, it is really fun, nasty surprise for the infantry and it used to (still does?) deal a ton of damage close range vs armor.
Armor piercing shells is a must have for the Panzer IV
