Ah, but I liked looking like Swiss cheese... wait, I already do with the Mutz anyways with all the shell holes created when tanks even glance in its general direction.
(Bad) Joking aside, I suppose that makes sense. Not really sure how I never actually noticed the resemblance between the two until I looked at pictures of both side-by-side, but I can see it now. BTW, one bug I saw in patch 9.15 with the Mutz remodel was that the gun would look like it was pointing in the opposite direction if you zoomed out too far while looking at it (as in, the gun would point through the back of the turret when it was actually faced forwards) Seems like a LOD bug to me, but IDK if this still happens in 9.15.1 (I've yet to actually see one in battle or drive it myself).
Oh, and as for the T49 hull, sounds good. I personally think the standard T49 hull actually looks better than the Sheridan's hull, especially in-game. Plus, AFAIK, the size difference between the two is pretty substantial, so it would most likely make things a bit more confusing while shooting at T49s.
I noticed that zooming out and reverse gun direction with quite a few tanks. i don't think it is due to the skin on the Mutz, but more a problem with the mod. I assume you are using a mod that allows you to zoom WAY out. The normal zoom doesn't have this problem.
