None of that actually requires development time. It's just extra servers.

Well this shows how much you know about what happened.
SE changed the requirements and limitations for purchasing a house. When those extra wards were launched you could not purchase a private home if you already had one with any character on that server, and you could not purchase a fc house if any characters on that server was in a fc that already had one. On top of that they added a randomised timer to placards to prevent house flipping. Introducing all of this does require development time.
What we need is for them to correct their mistakes after launch.
Patch 5.0: Viera/Vii Females, and Hrothgar/Ronso Males. New Tank, and DPS.
Patch 5.1: Viera/Vii Men are added in.
Patch 5.2: Hrothgar/Ronso Women are added in.
Patch 5.3: Glasses are made visible on the new races. A new healer could be patched around this time, or in a later 5.x patch if they still have time for it. So long as they don't implement any more limited jobs.
