Server Transfer/Faction change.

Q u o t e:
At this very moment my shaman is undergoing a faction change, am I able to do a server transfer at the same time or do I have to wait for the faction change to be completed?

You need to wait for the first transaction to finish AND log into that character - then request the next one.

There are a few issues that can be totally avoided by logging into the character between steps.

Q u o t e:
hey ,so say i didnt log into the character after i server trasnfered him, and initiated a faction change right away (without logging into the character first) what kind of complications are we talking about? because i transfered a character and then initiated the faction change this was on thursday night.... still says hes pending

Really depends, and often this doesn't come up at all.

There can be complications with Loremaster type achievements and a few other conversion type issues.

Logging into the character between steps can eliminate this as even a possibility of popping up.
