The Re 2005 VDM should be 6.0 seing as it does not compare to smth like the spitfire lf mk9 which is at a lower br. Seeing as the VDM version of the re 2005 is inferior to the normal re 2005 both in bomb capacity as well as in overall stats i think 6.0 would make way more sence. That would also help make it somewhat more “unique” compared to the tech tree version as it would be playable with 6.0 tanks like the Tigris R3, leopard 40/70 m18 etc.
