Your comparison is great if comparing to the 6.1 changes that samurai received, but to be clear, that bit you quoted was in response to someone suggesting that Kaiten be brought back as a passive bar that filled up over time and enabled the Kaiten effect when full to automatically buff your next weaponskill.
That said, I didn't quote the post I was responding to apparently, so that must have been extremely unclear - apologies for the confusing post - we were responding pretty rapidly at the time. x_x
