I'm actually hoping that the marine-equal ork classes will be "badass elite" orks. Like nobs, mega nobs, Stormboy nobs, Loota nobs, and of course Flash Gitz! These are the tuffest, meanest, greenest and shootiest/stompiest of all da boyz, and it won't rape canon to have them go 1vs1 on marines as equals. (same goes for Eldar, but with other elites like Exarchs, Warlocks, Wraithguards etc) But I would prefer it if the free to play boyz (or any other later added free to play class, maybe IG for Sm, Cultist for CSM?) would be a much more weaker , "mob" type of enemy. That would allow the lore to be somewhat preserved, while orks would still have the elite classes that could go head on head with the marines in a balanced way. Or let the free to play boyz distract them and than clobber da lot, but now i'm thinking like a sneaky Blood Axe.
I'd say Nobs would be too good, as a Nob is twice as 'ard as Maine boyz. Flash Gits, Tanbustas, Kommandos, etc would make good classes imo.
I think that depends on the Nob in question. After all, not all nobs are equal. Especially Mega Armored ones, the best of the bunch! Anyway, I would think that orks and eldar playing elites would be a good idea. Who would not want to play as Spookums, and try hiding in lava?
Yeah. Marines tend to stay the same as you go up in rank-you're still a power armoured giant, so a Tactical Marine/Librarian wouldn't play all that differently. Eldar get MUCH better armour and weapons, and Orks get tougher, stronger, more wounds, better armour, and MOAR DAKKA.
I'm sure you will be able to multi faction but if I'm anything like WoW I'll have too many toons and not enough time .
