I'm not a Fan of TrinmxxT. If you want another Reducer use Ulrich, because he has the better reduction ability and you don't really care if Uranus and GraksmxxT have their bonus. They are great without it, but your Piranahs are the chars waiting to win their rounds. I could even see you running 5 Piranah and only the great -5 reducers from Sakrohm.
Morphun (Eklore for your next 4 levels)
would be my go.
Makes sense TrinmxxT to Ulrich is a good call... but id play Raeth or Kristin instead of Bloodh ... Bloodh is just plain bad in my opinion.
Go ahead with Raezj over Bloodh..
I havent't tested Bloodh myself, was just the first big Piranah I thought off. Imho Raeth > Kristin btw.
