The command P4 won't beat any mediums, heavy RNG aside.
The self-buff makes the unit more durable than it is necessary and could be removed.
I'm in favour of how the current aura works, because the previous sector-based aura wasn't intuitive at all.
I also wouldn't want to give this unit the "T34-85 treatment" because it is one of the few units that allows skipping T3 and makes T4 builds somewhat reasonable and not just a fairytale. Otherwise there's not that much incentive over a regular P4.
What makes the command P4 perceived as overpowered is mainly the combination with (vet 3-) lmg grens and pak walls, which on their own perform at the peak compared to their counterparts. Throw in a Puma and factor in the non-existent teching cost and you got yourself a very deadly and affordable unit composition in the mid-game.
Therefore i believe the mobile defense commander is easily one of the best (if not the best against USF) commander in 1v1, which only lacks in the late-game.
If you would remove the self-buff i don't think the command P4 constitutes as a huge problem per se... it's more the combination and synergy with other units (cost-efficient long range infantry, best sniper, best mg, best at gun) that makes it really scary.
I think perhaps I may have used the wrong language in associating pz4 command tanks effectiveness against other mediums. But because of this misstep I think it would be foolish to give the unit a pass. When you say "perceived as overpowered" you are basically implying that it isn't, correct? But what I find interesting is that you go on to describe the very same point I make in this unit's very efficient role in the Wehrmacht army. This units enormous endurance buff to already several of the best core units in the ENTIRE GAME make it quite for a frustrating experience. You also describe the non- existent teching cost associated with this strategy. So it seems to me that you and I are not very different in our assessments of this unit itself and the role it plays. If you disagree with my conclusion please explain further, I am very interested in your response.
And just another note. In high level 1v1 play this unit, vs USF, is arguably, and I mean this seriously, close to a win button. I will re-iterate this again. The amount of resources you must use to combat this unit ( along with the core that it buffs) effectively far exceeds the amount that is used to create it. That alone should be an indicator that the unit is over performing in its role.
And another point on the discussion this thread has brought. I find that many people who reply to this thread make very un - sophisticated arguments that provide no value to this discussion. Merely saying " This unit is fine dont touch it ". If you really believe this unit deserves a pass, provide logical evidence in your argument that this unit is not over performing in 1v1. ( The game mode that balance making decisions are mainly catered for ).
