Protector of Cantha Title

....Which pretty much means that you have finished the Factions Campaign,

my question is that the title requires that you have all 13 missions complete, but guildwiki says that there are only 12, I have done every mission except raisu pavilion and imperial sanctum on the kurzick track but my hero track only displays 6 missions completed. Do I have to go through the luxon area as well to get all 13 missions, even if the wiki's say that its not necessary? (im going anyway just to get my cartographers title)

Yes. You need to do both Gyala Hatchery and Eternal grove missions to get the title. Not to finish the game, but for the title, yes.

On the good side, you only need to do one Vizunah square

You need to get masters on all the missions for them to count towards the title. Likewise, you need to do both Gyala Hatchery and Eternal Grove. This unfortunately means you need to get 10000 faction to whichever faction you don't belong, in order to get to the mission.

For protector of Cantha you have to obtain Masters for it to count towards the title.

Tyria missions - Primary Objective & Secondary/Bonus Objective
Cantha missions - Standard/Normal Reward, Expert Reward, Masters Reward.
Elona missions - Standard/Normal Reward, Expert Reward, Masters Reward.

Tyria Protector and Guardian, all missions have to hae Primary and Secondary/Bonus Objectives completed.
Cantha Protector and Guardian, all missions must be completed with the Masters Reward.
Elona Protector and Guardian, all missions must be completed with the Masters Reward.

And yes, this includes the missions you did not have to complete to move foward through the game, Luxon or Kurzick in Cantha and in Elona the missions you didn't have to do depending on the heroes and paths you chose while playing through the storyline, Margid or Master of Whispers, save Ronjok or save the Garden.

You also don't have to do Unwaking Waters twice.
