The PIVs are terribad, full stop. Even if you actually get lucky and receive them with vetted crews, they come to late to have an impact as a generalist tank and they are outmatched against all Allied medium/heavies except the T34/76 and the vanilla Shermans, against which they do ok-ish. If you need serious AT, this is not it, and at that stage of the game where facing Jacksons, ISUs, IS-2s, or the advanced Allied mediums is almost guaranteed, you don't want to sink your fuel into such a lacklustre unit.
Couldn't agree more. I've pulled elite armored from my loadout. The only thing i would even want from it at this point is heat shells and those sound like they are bugged. I'd take a command panther over the p4 battle group any time.
