The Kugelblitz is the only vehicle in the German tree with a Battle Rating (BR) of 7.0, leaving it without a proper lineup. In contrast, the 6.7 German lineup is deficient in anti-air options, forcing players to choose between using the 6.0 Zerstörer 45 or up-tiering the entire lineup to include the Kugelblitz.
Furthermore, the Zerstörer 45 has twice the firepower at a lower BR, and the Kugelblitz’s roof armor only provides protection against non-armor-piercing rounds from aircraft. In my opinion, it doesn’t deserve such a high BR compared to the Zerstörer.
Given these points, wouldn’t it make sense to lower the Kugel’s BR to 6.7? This would make it useful in one of the most popular mid-tier BR lineup.
