1)point is lost due to the fact that Land Raider aka weaponized dozer, exists and is transported by Thunderhawks. This vehicle is VERY expensive and complex by Imperial standarts, but it IS utilized by Space Marines. Meaning that quite often there are instances where slow speed is not a problem and superior armor and weaponry more then make up for it. Leman Russ is much cheaper and lighter and while it certainly wouldn't perform anywhere near Land Raider, you can deploy several of them and still get profit in comparison. Even IG Leman Russes have a lot high quality specialised versions, just imagine reoutfitting them with Astartes class weaponry and tech.

And yeah, they're officially not allowed to have tanks. It is mentioned somewhere as being one of the conditions of Codex Astartes that ensures that if they rebel, they'll still have weaknesses that IG can exploit.



2)I never mentioned them, but the other guy, who thought that empty show off with nonexistant numbers would mean anything, did so. I'm not a fan of superheavies as they're very limited in their use: siege assault and defense in cities and prepared defense lines as well as hunting other superheavies, knights and light titans.

Baneblade and it's variants aren't lost, but if you want to have something that is even lighter and cheaper in production without falling down to Leman Russ level then I present you with Malcador and Macharius heavy tanks. They're obsolete as f//ck, but so was czechoslovakian Pz.35's that became a basis for Hetzer, most successfull vehicle of Wermacht. Just put spare parts from Land Raider on them carefully keeping them under overweight limit that would kill them for good and you'll get some pretty usefull vehicles for cheap.
