About your question on the forum about the Unclean puke, when I play Space Marine and I'm going melee against him, if I get hit by the puke, I take nearly no damage and get knocked, and that's it.

When I play a more fragile class such as Sorcerer or Tau without (heavy) shield, I just never get hit because I'm constantly trying to avoid him. The puke seems to be far less dangerous than his normal attacks (which can hit adjacent targets).
