May I, in that case, have my GA Vet mounted on a fucking Juggernaut?

Yes it do. Just checked Chao Space Marine Codex.

So can i randomly morph into a Demon prince because it is in the codex?

Don't you also have a chance to be a spawn or a trash demon?

90% chance of shit and 10% chance of god hood!

I support this mechanic as a kill streak reward for an elite class or something (when its implemented one day)

Unless you are actually the Warlord a chaos spawn is still an upgrade powerwise for Squad leaders.

I still gotz duh rulez fer squatz....

Demiurg Brotherhood... Responding.

I support sorcerers having jump packs.

Why the fuck not? This game desperately needs more options and a feeling of identity in the sub-factions beyond a few different poorly voiced taunts.

If/when they release Elites, having an Elite version of the Sanguinary Priest with a Jump Pack would probably be a thing for Blood Angels.

HA! Dem ladz at GW kudn't reezist duh urge t'put dem stuntiez bak in duh game!
