Heros..where art thou?

I was wondering where I can find all the HEROS in Nightfall? I know this may be a spoiler for some. But I've found the necro. and am looking for more. Any thoughts and help is great.

You'll start to find them as soon as you start to do the quests for Nightfall.

you gain several by doing the very first quest when you get ot Nightfall if you'r efrom Tyria, but you can also get any of the ones you missed during the game at the end of the game by talking to them and doing a quick quest.

You can get necro at Lions Arch in Prophecies.

You can get assassin at Kaineng Center in Factions.

All others are given to you during progress of Nightfall. You cannot hurry their acquisition.

Several times during the game you will be given a choice of two heroes. The hero you did not choose will be available at the end of the game.

Oh ok thank you!@
