That's because ele can't shoot on the move.... none of super heavy TDs can.
And that is good, but why not balance meter units and nerf change that actual balance destroyers like Ele and Jagdtiger.
Panther is a hunter, Jackson and Firefly are long-ranger. Nerfing the hunt performance for These two is only logical.
Panther only has 50 range and ~ accuracy.
But Firefly and Jackson have WAY to much accuracy for the 60 range. I am for give them same accuracy as Panther, but give them my move/stop mechanism. If they are stationry they get 60 range, on move nerf to 50.
After that Ele and Jagdtiger can get longer reload etc. because they arn't needed for balance anymore.
Edit: This mechanism can be also made for SU85 with ist sight ability. If it is activated it gets 60 range, when not it has 55 range.
Also Ele can get back this option, like it was 4 years ago.
So that Units get more handycaps.
