It's not really OP. Can be toxic on some maps, eg. placing it defensively on Lienne forest on the right side of the bottom fuel can easily lock out any infantry advances. Also it's quite far from indirects like pak howi and mortars. Also, the other approach is through a narrow gap inside a forest, which can be a death trap. Combine it with it's lethal cannon (it often wipes a whole squad in 3-4 shots), it can be a menace. On the other hand, OKW will invest into defending it, so that gives you some breathing room.
It all depends on the map. The Schwerer is not really OP, being static and unable to ground target. It's strong on large maps where you can place it defensively, making it only killable by a deep dive (which is in itself risky) or offmap (lots of muni investment).
If I was forced to change it, I'd reduce lethality and increase suppression. So that it will not just straight wipe in a couple of seconds, but rather suppress. I'd also make it scale with range, less suppression and lethality at max range, more so the closer you are. I'd also increase close range penetration if need be, so that if you run around it with a t34, you won't be as safe as you think. And it wouldn't just instantly suppress/kill at max range if you run into it
I've destroyed many a schwerer as USF. It usually takes about 5 barrages from 2 pak howis to kill it (I always play dual pak howi, so 2 barrages from both, which is 4, and then one more from any pak howi).
I've also had many a schwerer destroyed by brits. But as I play OKW only in custom games, I always place the schwerer near the frontlines for the shi** and giggles.
It's definitely not OP. Wipey and strong, but not OP due to the sole fact that it's static.
Cancerous on teamgame maps like Redball, Lienne, etc. but quite normal on 1v1 maps and some 2v2.
In most teamgames scenarios, you want to scout ahead with infantry as you will almost exclusively encounter a raketen/pak wall, especially in 3v3+. So you want to scout and push with infantry first, which can instantly be shut down by a single schwerer. Then you know there is a schwerer and you know that you can't just push, so you invest time and money into destroying it first, which makes you vulnerable to pushes. On the other hand, if you manage to destroy the Schwerer, you demoralize most opponents and buy yourself some time. Against well coordinated opponents, schwerer will be most toxic and well placed and defended, denying infantry/LV advances. Against randoms, destroy it and one will rage, even if top 20.
