I don’t know if I’m failing to explain myself or if you’re skimming my comments, so let me put some emphasis on what I actually said.
An incentive.
Individually, if you forget the match as a whole, the Pz IV does better at range, so you (especially if you’re inexperienced) are tempted to play it like that. However, if you are an experienced player, you know that most of the time, the team that sits back and snipes is the team that loses. So, you do just like you said, you push forward with whatever vehicle you have.
However, the Pz IV is not good at brawling. You can make it work anyway, but it will be less competitive than some of its competition. It’s that simple.
Given the very limited traverse angles, you’re mostly aiming with your hull, and the JPz IV turns so well that it’s much easier to get the gun on target. The flat ballistics also mean it takes you less time to aim. The slow vertical guidance both vehicles share is a much bigger handicap for the ballistics of the big donk HE.
I love the Brummbar but it isn’t meta at all.
I feel like a broken record at this point. Yes, it can be used, but we’re not talking about what can be used, we’re talking about competitiveness. You can brawl in a Jagdtiger too, god knows I’ve done it, but you’d be better off in a meta vehicle.
War Thunder follows the 80-20 rule. 20% of the team does 80% of the work. If you want to win consistently, you have to be able to do everything. Planes in the sky? You gotta shoot them down. A whole flank is empty because the team ignored it? You have to go there. A cap needs contesting before tickets run out and no one’s pushing it? You have to do it yourself.
If you’re in a vehicle that can allow you to do most or all of those things, you will win more often. No doubt about it. That’s the definition of “meta”.
Tank destroyers are fun to play, but they are much more limited.
I have something like 3k matches in the Jagdtiger alone. It’s fun, I love it, it’s my special autism machine. And yet, I must tell you, almost every time I spawn it I find myself thinking, if I’d spawned the Tiger II instead I would be having an easier time killing the same opponents and I would be able to carry the match much better.
What’s fun, what can be used in a pinch, and what’s competitive are very different things.
