I think maybe Tightrope made a video on it. Not 100% sure. Either way, I've been including it in my 4v4 loadout along with the bulletin that makes it build 50% faster. The only actually impactful bulletin in the game lmao.
Best thing about the Pak43 is you can smash superfluous new assholes into enemy tanks then willfully deconstruct it for a return of 150mp and 15 fuel, effectively a 200mp and 30 fuel counter to all tanks.
EDIT: oh and with 2 engineers and that bulletin, you can build it in about 20 seconds or so. Good for suprise attacks.
EDIT 2: to begin deconstruction it needs to be out of combat for like 15 seconds or something, but once you begin it can't be stopped unless the gun is decrewed.
I agree with you and I also use it, even though the commanders to which it is attached both on OKW and OST are mediocre at best.
I agree with the overall sentiment however and that's because I came to the conclusion long ago that medium tank rushes are so out of fucking date it's almost ridiculous to bring one. By the point even the fastest timing medium tank rolls (T34/76) the enemy should have atleast 2 snare-capable squads plus an ATG which believe it or not effectively make it unplayable and ineffective.
I would much rather turtle with ATG and MGs and hold on to more potent machines than this shit. Especially as OKW, where you can fight for 25mins and then bring the best tank ever (Konigs). If that's the situation I face then sure, I will bring a PAK43 along with some trenches and flaks.
