AT guns. Offmap. Artillery. Bazookas.
What if ele owner is not AFK?
Now everything can drive there and defeat it. No sense in an Elefant if exactly the thing it is supposed to hard counter hard counters the Elefant. No need to go for a thing that can´t fight infantry and can´t fight mediums. That leaves the Elefant to counter two units in the game: The IS-2 and the ISU. Hardly worth going for it imo.
Extremely flawed logic.
Unless you believe that tanks shouldn't be able to counter AT guns, because AT guns are supposed to hardcounter tanks.
Ele 2 shots mediums. If that isn't hardcountering, I don't know what is.
You need to defend it?
Well guess what?
No undefended unit will last long on its own, this is how the game works, if you don't cover for your shit with combined arms(aka 2 paks in the back in this case), then you lose shit.
Other player managed to get a couple of tanks ?BEHIND your super heavy TD?
Congrats, you got outplayed/didn't anticipated/don't know what tellers are/had AT guns god knows where, but not in the place they were supposed to be.
If you don't know units weaknesses and how to cover up for them, you'll be losing units regardless of how strong they are on their own.
