I am not agreeing with Vipper's general point, but the map design in large modes absolutely dictates you to pick 1 or 2 commanders, otherwise you have lost. It is good that you have to adjust your playstyle to the maps, but in many cases it is a bit too much.
Ostheer mostly relies on Panthers though in the late game since PaKs regularly get eaten by arty to (best case) reset the veterancy or worst case destroy the whole thing.
Tbh, all factions relay on their top end TD because ATGs get decrewed easily, and now its going to be even easier to do so. But I do see your point about the maps.
Your personal quarrels with Vipper fit better into a PM.
It was not personal attack (if it was I'd be more creative), but actual description of what he does in games.
You'll see what I mean here when you'll be blessed of being matched up with or against him, you'll instantly understand why everything is problematic to him.
In what I agree though is that an Ele/JT is by far the most reliable way to shut down Allied TDs, PaKs are always vulnerable and JP4s only awayable to OKW plus they will need constant repairs, whereas you can safely take pot shots with an Elefant and win on the micro game and repair less than others. That's why it is overly popular.
True, but that stems from team games specifically, the resource inflation and overabundance of fuel, resulting in easier time getting and replacing armor then it is in 1s where map is constantly contested or 2s, where the only reason to get ele/jt is ISU and the latter is getting another heavy nerf now.
Its a need that originates from circumstances of game modes, not from effectiveness of TDs themselves.
In 2s you can do fine without it, but above that its mandatory.
