Just like 2 years ago, the situation with 3D styles for Tier 10 tanks remains ambiguous. Not a single reward tank from personal missions has received a 3D style [and that’s the most disappointing part]. The art department hasn’t managed to establish a practice or even do it once so that a researchable Tier 10 tank has its own style right at release!
It seems no one really knows how tanks are selected for 3D style designs (the latest SPG was supposed to get its 3D style in the New Year boxes, and at least one collector’s tank too—but that didn’t happen either. Instead, we got styles for Tier 9 tanks. And as for the Japanese Ho-Ri 3, it seems like everyone just completely forgot about it).
