I seem to have voted Biel-tan... well, that and Iybraesil is more like it, but there's only Biel-tan, so that it is.
I can at least understand why you have chosen these four craftworlds. They're the largest. Although I do understand my compatriots' desires to have the smaller, lesser-loved craftworlds a moment in the limelight. Assuming the game works out well, they should have plenty of time to try different craftworlds though! Starting with the big popular ones just makes sense, as they can always go for Saim-Hann, Yme-Loc and the others in the future.
Aye, true =) It would be really nice tho if they'd mix the Craftworlds they first introduce to the game. Like a 50-50% minor/major ones =) So that way there would be some well known ones (like, Biel-Tan and Ulthwé) and some lesser ones that still has nice story (like Mymeara and Il-Kaithe) =)
Altough Saim-Hann, being the "model" Craftworld in the 6th edition Codex (and being quite large in fluff) will most likely be included in launch. More like than Iyanden, anyway.
Aye, Iyanden sadly I could only see as an NPC faction, since their numbers dwindled so much, they need to rely on wraith walkers and other constructs to field any kind of combat ready army :/ However much I like Iyanden, I cant see them as a playable faction.
Iyanden could certainly help our numbers... PC spiritseers guiding AI wraithguard would be pretty metal. (not happening though, would be a tad absurd)
Actually I think it would be: 1. Awesome :3 2. A solid and viable pet-class 3. Lore friendly ^^ 4. We need the wraithguard/blades to counter some heavy stuff 5. I'd be sold for life for the class if they implement it *-* I LOVE warlocks and the Wraith walkers ^^
1. yes, 2. see below, 3. yes, 4. see my 2., 5. I think many of us are sold for life if they make the game awesome. Oh, I have the feeling they'll include them to some extent, but not AI. Just each person can play a wraithguard and there's a spiritseer nearby backing them up. If they ran around as pets then that one spiritseer would be roflstomping a lot of people.
