I haven't done the berserker epic.

For paladin epic 1.5 pretty much everything is NO TRADE. Cleric likewise. And druid. And ranger. Chanter had some droppable stuff but also some NO TRADE. Most of the epic 1.5 tradeskill stuff I'm aware of has to be done by the character in question. And I think that's perfectly appropriate.

Considering that brewing 1-200 takes about 1 hour to achieve I don't think there's much to complain about here.
