Unless they have changed things, Mage pets are way OP. During my time on Fippy, I tried a mixed group of SHD, CLR, ENC, WIZ, MAG, SHM and did not have very good results.

Then I made a 5 Mage and CLR group and started mowing down mobs. Dungeons were still tough due to aggro issues (nothing like an errant mage pet bringing back a pack of 20 mobs). If you are looking just to goof around, I'd try the 5x Mage + CLR route.
