And where exactly is the need to make yet another thread, instead of just bumping the existing one you made on the exact same topic?

On the topic itself, there are quite a few classes without a self heal, they can just cross class the gimped (untraited) version of second wind that barey does anything. It's still a self heal, however the only reason to cross class it is the pure lack of better options, I'm pretty sure if there were better ones, SW would be the first thing to be switched out for most Nin/Drg/Brd players.
