Haha seriously though, there could be two possibilities:
1) Samurai being the dps/healer. With the additional healer/dps (chemist/gunner), we'll get the complete holy trinity upon expansion.
2) Samurai being the tank. We'll then end up with 4 tanks, 6 dps, and 2+1 healers. It would then be more likely that we'll get another healer to end up as 4:6:4 to balance things out.
