If puma becomes a 5cp call-in unit again, the other skills must be changed accordingly.
It's too OP to have Command pz4, ostruppen, and panzer tactiction with Puma.
The right direction is to save the commander's unique concept by allowing the puma to be used again and changing other skills.
The nightmare will repeat if Puma becomes a 5cp call-in unit again without any changes in other skills.
This commander was meta shortly after I started CoH again, so correct me if I'm wrong.
But will this really be the case?
USF can go against OST without the need for an AI focussed LV. The Stuart is not great against zhe Puma but it can survive without too much trouble. Against Brits you do not need a Puma, and Brits don't have a reason to counter have problems with a Puma, because their only LV is basically a Puma by iself (concept wise, not total stats).
So the major issue is (and I think also was) against SOV. At the time Soviet T1 was meta because of poor Conscript scaling. Which also means that you are susceptible vs a 251 and 222, so you need a LV to survive the early-mid game, which was usually the T70. And that was completely shut down by the Puma.
Now with Conscript T2 builds all of this works slightly differently due to the available PaK and less need for a LV. Now obviously there can still be huge issues vs T1 builds, but saying it will be as bad as during that time is likely an overexaggeration in my eyes.
