That's bullshit and you know it, anon.
Black Templar got jump pack Marine, so do Vanilla Marines. Tac Marines as Crusaders, Scouts as Neophytes (oh boo-hoo, you can't have them all in one squad, that's too bad), terminators, etc. etc. What's the problem? Can't get the champion? Use a captain with relic blade and shields. Have some creativity, you thankless piece of shit. I tell ya, if Gav was here, he'd get grimdark on your ass for being such a rules lawyer and not being able to work without the restrictive rules.
Space Wolves. jump-packless assault marines as blood claws... I can't think of anything else. Why can't you just use normal sergeants instead of Wolf Guard units split around? All your conversions will go to ruin? Tell it to the hand.
Dark Angels? Gimme a break. Apart from getting Troop bikers, which Vanilla Marines get too, you just need to make Troop terminators available and paint them white, and voilá, Deathwing terminators. Oh, the "rules" ain't exactly the same, eh? Well, tough titty. I'm sure my IG is a little pissed about losing this and that with the doctrines, but hey, I got over it, you'll get too. And if you don't, I'm sure GW will still keep making money like a Swiss banker during WW2.
