Yalahar quest: Can I do only bad side missions but choose the good side on the "Decision Mission"?

Question

Imagine the following:

I wanna do only the bad side missions, so I get the achievement "Follower of Azerus".
But I also wanna have the outfit from the good side, because I like it better and I want the achievement "Yalahari of Wisdom".
So... Can I do all of Yalahari missions on bad side and, at mission 9 "Decision Mission", choose the good side? Or is it just "too late"?
Thanks 

Answer 1

Yes, you can change sides on the last mission and you even get an achievment for this change “Turncoat”

According to english tibiawiki
 It says we get no achievement

Well I did all bad side missions and chose good side in the “Decision Mission” and got “turncoat “ achievement maybe it is wrong on the english wiki, it says nothing of not receiving achievements in other wikis…
