In a few years we will find out that the Vipper account was just part of a social experiment: "How long will people continue to talk to you if you choose to ignore their argument and instead try to disprove single sentences without the context?"
or in few year from now you might learn the game mechanics.
or
you might even understand that I am not the one continuing this but you by mentioning my name and writing things that are simply false
Having the 75mm-HE AI-capabilities and the 75mm-AP AT-capabilities in one shell would be stronger than having to switch between the two shell types to fight specific targets, right? Thats what was meant with "shell switch is a disadvantage". But because there is no medium tank shell that has as good AI as the 75mm-HE AND as good AT as the 75mm-AP that makes up for the disadvantage of having to switch to the correct shell. This makes the performance of the 75mm sherman balanced and switching between the shell types an interesting choice. How this can be misunderstood is beyond me and has to be purposeful derailing of the actual discussion.
And you are simply wrong.
What has been said is that:
"The shell switch alone (6 seconds) is already a big disadvantage at fighting different targets, so this surely would not be op."
That simply false.
According to that claim, if one is driving around his 76mm Sherman with his AP round load and vehicle comes he should immediately switch rounds and wait 6 second to load a HAVP.
That would be bad play and not a disadvantage of 76mm Sherman.
On should simply fire the AP round (which is actually one of the best AT rounds in any medium tank) and if the enemy vehicles has high a armor value switch to HVAP immediately after firing. The time to switch would be close to a normal reload but one would now have access to AT shell (mostly) restricted to TDs.
The "switch rounds argument" is imaginary disadvantage that was also attributed to 75mm and HE round.
It would only made some sense if both rounds did damage only and exclusively at one type of target. That is simply not the case.
Sherman AP rounds are good/great AT rounds compared to other medium tanks and average AI rounds compared to other meduim tanks.
Shermans using AP rounds can engage all targets.
On top of their multi role rounds, Shermans have the option to use a superior round against specific targets.
That is no way a disadvantage for the unit.
