Other - Second Group Makeup

[Naturesong]

Hi, I'm playing on Laz and looking for some input into my second group/s.

I have available the following classes:
shadowknight, paladin
bard
shaman
rogue, berzerker
beastlord, ranger
wizard, necro

And I'm looking to make up two groups. Each group will share the bard and shaman. And have as tank either sk or pal.
This also gives each group 2 FES for grinding.

Group 1:

• ShadowKnight
• Bard
• Shaman

Group 2:

• Paladin
• Bard
• Shaman

Looking for how best to allocate the remainder of the classes.
Loosely I'm thinking sk group to include the pure melee and ranger, and the pal group to include the bst and casters.

What do you think?
