Sounds awesome. I havent seen ANY dungeons yet, let alone "expert" ones, and im only level 15ish so I have no idea what will be required.

I decided to do same as you though and pick 1 of each archetype so I could try out different stuff when i hit 50.

I went with (for leveling at least) the classes that seemed fun to me.

Right now I am planning:

1 - Champion / beastmaster / reaver
2 - Ranger / Bard
3 - Druid / justicar / shaman
4 - Necro / chloro
5 - Archon / chloro

My two biggest (obvious) issues are probably going to be:

-my warrior isnt very tanky and
-i dont really have a "main" healer.

We'll see how it goes =P
