Personally. Nin doesn't need a buff, if they buff nin. It'll just right back to WE NEED NIN, OMG IF WE HAD NIN WE WOULD HAVE CLEARED.

Nin is probably a very "trick"y job to buff honestly. Because if they buff it too much, it'll just make people think they NEED ninja. If they keep it the way it is, ok even I'll admit. Its probably a dead job and only for people that truely enjoy it...but hey.
Now nin's know how us sam's felt back in sigma.
