I don't think it is greed as much as it is smart business sense. They want to capitalize on the rarity of them and an event being the only way to get them before Kage Treasure comes about later makes sense. If you want the ninjas early, you'll pay/work for them. Otherwise you take your chances with the draws. That's pretty much how it is. However, greed would factor in depending on just how much they're asking for said ninjas. That's all about perspective though.

I'm sure if he is they will ask far too much for him. If it's reasonable though I'll pick him up(I.e. around the hundred mark or so. I expect three or four times that much though.)

I'd be excited if the chance wasn't .00000000001 percent to actually pull him from them.

If Sage Naruto is available, I'll pick up as many frags as I can; hopefully enough to get him outright via spending if it's within reason.
