Keep the cleric, rezzing in combat will save you more headaches for when your macros fail/freeze etc. Also the auras are great.
----Once your crew has alot of AA's and geared up, especially your Tank, swap out a shammy.
Once you have a Beastlord in your group, you will not ever wanna go back. The Swiss Army Knife can just fill in almost every gap.
Add the BL, and if you wanna use a 2nd zerker dump the rogue.
