I am a huge fan of avoiding overlap... that said, I would change out 2 of those berserkers for a BL and a rogue (or Monk, I like Master's Aura when you don't have the Enchanter for guaranteed Mez'ing and/or Absorbs; and for solo healing)...
Furthermore, I echo @Sic by simply stating that SK > PAL > WAR, in that order for me, brings SOOOOO much more to the group game; warriors are huge HP POOL Meatshields for raids, that's about it for me... SK's and PALs bring so much more to the group content side of the game...
Just my two
red
ents.
