Guild Wars 2

I don’t understand why I can’t complete this. I have done it twice now on different chars. I do it in order and use the skills when the Adepts say but I have only 3 of 5. I have spoken to them all but it doesn’t update. The first time I went in to the new area I didn’t do it correctly but made my way up top the top and spoke to them all in the end. Even if I do it on a new char correctly first time it won’t update. Is this a bug or is correct that you can’t get the achievement if you don’t do it right first time?

Just about got enough karma to get an armour set from the temples in Orr but not sure what to get. Is it best to get a full set from one vendor like Balth or is it getter to get different pieces from different vendors e.g. power, tough, vit, stats for all pieces. All the runes will be different but you can always put others in instead. A full set does give a range of stats across the board and a full set of one rune type. Just wondered if anyone has any thoughts.
