The elevation and collision issue has been known for years. With the Commander Revamp Patch follow-up patches we've spent weeks trying to tweak it but it's impossible to get any positive results without deeper access to animations and core mechanics, which we do not have.
Accuracy for the shell was already set to 100% (or rather, scatter to 1). Doesn't work.
But thing is, it WORKED before. It was USABLE before. After the adjustments I haven't seen it once outside the initial week after patch, and even then there it was no threat. All it needed was a damage reorganization not a removal of literally every trait that made it usable ( as seen by previous attempts to rebalance the ST by making removing its piercing and its range, but back then it still hit like a truck and it was STILL a death sentence for the unit)
Now it's a big lumbering waste of fuel and pop thay shoots once over minute to, if it's lucky, kill a couple of models here and there. It's not going to put fear in blobs since you will see it coming and aiming and when it hits, even if the shell makes it to target, isn't going to do anything meaningful. even emplacements that can't flee from are safe because it doesn't deal enough damage to warrant its cost and micro even before factoring in brace.
You guys have done a great job taking useless units and making them viable, but the sturmtiger is a rare case where you did the absolute opposite and completely patched a useuable but niche unit right out of the game.
Consider that the sturmtiger also locks out the king tiger. Why would anyone ever chose the sturmtiger over a regular KT, let alone one that can call in arty and has HEAT SHELLS? It's not even attractive pick vs what is often regarded as an over priced hunk of garbage...
