So my friend finally got his computer fixed and hes thinking of making a Druid (hes linked to my account as well). What are some good trios to set up with a druid...Im figuring just about anything can be. Some ideas i was having

Druid/Rogue/Warlock
Druid/Druid/Mage
Druid/Sham/Warlock

I understand the trio can be a lot of whatever, but has anyone had any good synergy style groups that worked real well for them?
