Kv8 is useless in front of shreck blobs. As a primary anti infantry tank its role must not be limited to clearing only garrisons. For that we have flamer engineers. By the time it comes enemy usually has roaming blobs of shreks and a panzer 4. Believe it or not a panzer 4 can easily penetrate it from rear as kv is quite slow. And shrecks do the main deal. Fire doesn't really kill as fast as it makes you believe. Now if you compare to the OST halftrack. That fire does immense damage to infantry and squads. If you are a second late in retreating that means the squad is lost. Now people can argue it has 2 flame projectors etc. Whatever. But kv 8 is not at all OP at this moment. Rather nothing really penetrates the high armor of brumbar. It 2 shots a Soviet squad and wham it evaporates.
Couple it with an ostwind and you have a combo only TD can counter. For which you have shreks. So yeah i think brumbar is fine where it is.
Its a non doctrinal tank. Keep it like that. No need to compare with a doctrinal tank which performs just okay.
To counter shreck blob add a hmg the flamethrower of the Vehicle will care little about the suppression modifiers.
PzIV has a 76% chance at max range to penetrate KV-8s rear/side armor. By attempting a flank it will probably also expose its rear/side armor (unless it manage to attack perpendicular) which KV-8 has a 67% chance to penetrate. Even so it need 6 shots that hit and penetrate to kills it.
AT 5.1 speed/1.4 acceleration it is about as fast as IS-2.
I am not aware of the vet hp bonus, its also not listed at coh2db.
It seems its mostly up to date on that site, but could be outdated ofcourse.
