Protector Title

I'm starting a new character, and I'm seeing how quick I can get my three protector titles. I started a factions character to get them to 20 asap. I was wondering -

Should I complete the campaign first, then get all the bonuses/master's?

Or

Should I do the bonuses/master's as I go along with them?

Thanks in advance

I'd advise you to start in NF, mainly because of the Heroes. Grab the 2 necros (MoW and Olias) and a monk.

1 MM, 1SS/Curse, 1 WoH/LoD should bring you through almost every mission, except a few.

If you know what you're doing, go for mission+bonus/master straight away.

Gl with it.

If you've done them before or you know what you're doing, then getting the bonus/masters is easily fit in along with the main mission, and sometimes it's easier to do the bonus then leave it (Gate of Madness, for example).

The fastest way to get all 3 Protector titles is by starting in Factions (not Nightfall!). After you get to level 20 you should get your heroes (play Nightfall until you obtain Master of Whispers or Margrid), maybe even go to Eye of the North for Ogden Stonehealer, Vekk, and Gwen (since you have to do very little work to get them). I'd focus on Factions first, since it's the easiest to get the Protector title.

But I don't think I understand your question; in order to finish the campaign, you have to do the missions... so you may as well get masters/bonus if you're going through them. I don't think there's any advantage in saving those for later.

I suggest you do them as you go along and Hero/Hench EVERYTHING.

I would have thought the fastest way is to go from Prophecies.

Yes you can get to lvl 20 faster in Factions, and yes you get heros early in Nightfall. However, I find it a pain to travel from Lion's Arch all the way to Great Northern Wall to get masters in quests that are easy enough to do without being lvl 20 with heros.

Since the Faction city missions on noob island and the city missions in Nightfall's noob island are easy too, at least you don't have to waste time to get to those cities and finish them.
