How do you actually get to Dalaran. It's really high up... can you only fly there?
Earlier in the beta, anyone could reach Dalaran by visiting the Crystalsong Forest and using a crystal below the city to teleport up. However, more recently, transport has been further restricted. To visit Dalaran one must be level 74 and complete a quest. (As I'm not yet level 74, I can't give you details on the quest, I've only been told it exists.) Commentor Ktok also notes that Mages get a self-only port to Dalaran at level 71.
The level 74 thing does seem a bit odd (can you imagine Shattrath with a level-restriction?), but we'll see if the restriction sticks around and makes it live.
Are professions fully implemented yet? If tailoring is implemented, what size bag can you make with the new cloth?
Though we did have some new professions info from the beta build that launched last night, still no tailoring.
I was wondering about the new calendar. We currently use a mod to coordinate raids/instances between two guilds. Will the new WoW calendar have this ability or is it limited to members of one's own guild? I know that there is the option to send invites to players, but that seems a pain to throw an invite to every member of our partner guild.
Currently, the calendar only allows you to manually invite players, one at a time. However, I don't think the calendar is complete yet -- even in last night's build it had some interface updates which provides you with more details on who has accepted your invitation and the class makeup of your group.
What are the rep rewards from the two starting zones? i.e. which one should I have my main do?
Reputation vendors currently sell nothing of interest, I'm afraid -- so it's too early to make that decision! However, both zones are quite fun and there's no reason (at least not in the present beta build) that you couldn't bounce between the two and earn reputation with both.
I understand that the Death Knight runes will not stack with enchants (i.e. mongoose or executioner). As Death Knights progress throughout the game they are bound to get new weapons. When they get a new weapon and put rune enchants onit, does the appearance of the weapon change to reflect the presence of runes?
Each rune option has its own graphical look, just like an enchant does. Check 'em out in our runeforging gallery!
Are there any repeatable reputation hand-ins for Netherweave/Frostweave?
I've looked through the capitol cities and seen nothing of that sort. Sorry!
