Note: It is likely that Tosan is being represented as a Monk instead of Hunter. This leaves Druid, Hunter, Mage, Rogue, Death Knight and Monk with only 1 NPC.
- The NPCs will be used in Ashran. When your team is behind they will come out and help you.
- The NPCs have a gameplay element and thus their race/faction/spec matters.
- Holinka teased that the Blizzcon winners might be getting their own NPCs (Sodah, Chanimal, Talbadar*) and he shut down Rzn and Snutz.
- Holinka confirmed there will be more EU NPCs.
Put the most likely candidates in bold and least likely in italics, mainly taking into consideration their spec and relations with Blizzard. This is purely my opinion and a guesstimate of the people Blizzard will most likely consider.
[US] - Snutz, Rzn, Reckful, Sodapoppin, Jahmilli, Dannycarey, Chanimal, Sodah, Abn, Pikaboo ...
[EU] - Minpojke, Zunniyaki, Nolifer, Boetar, Baten, Trillebartom, Doomsen, Akaishuichi, Nauree, Praii, Flubbah, Hydra, Mystic, Braindeadly, Waffle, Blukstack ...
Classes with only 1 representative so far and are thus most likely going to get more:
:druid: : Sodah, Sodapoppin, Minpojke, Baten, Doomsen
:hunter: : Braindeadly
:mage: : Jahmilli, Abn, Nolifer
:rogue: : Rzn, Reckful, Pikaboo, Akaishuichi, Praii
:deathknight: : --
:monk:: Dannycarey, Nauree
