You are suggesting for them to use event ninjas where they still can milk people from their money? It makes sense they would add rares from treasures.

Well, more like ninjas that have already been milked because of the change of meta. Or some ninjas that still have some room for milking but are past their prime. Jiraiya Young adult has been given away for free already, but some people don't have him. Normal Kushina hasn't appeared in ages and is just a meme ninja. Asuma and Nagato Edo well, they appear in events from time to time, but because we gotta do stuff for those points I don't think they're exactly "free", and I never expect them to be cheap, let's say one would be able to afford a couple of fragments.

Now in the case of Hanzo and Hinata cloak, I don't have any of them characters, maybe it would motivate me more to get their breakthrough if I actually had a way to get them, even if it's a few more fragments (and this way they can be milked too since you can buy point bundles for the shop). Rares from treasures are very helpful for younger servers, they don't have to disappear, but a balance for older servers would be appreciated.

Just because they have been milked in older servers, it does not mean it can't be milked for newer ones, especially to the low paying players who can afford these types of ninjas instead of the ones that cost 10k+. Items is what should be updated in my opinion. Having the refine pack would make sense as it would all players.

It appears based on previous events, if you want to get frags for skillbreaks you either have to either buy or wait until it comes out for free and I don't see them changing this mindset.

Hm yea that's a good point, although it wouldn't hurt to see from time to time someone marginally more interesting than Ao or Shurado. We get new ninjas almost every week, eventually the event only ones will outnumber the treasure ones and a bit more accesibility to fragments would be appreciated.

It is a good event, I just feel like I outgrown it, at least until they add and if they add new items.

Lets say adding advanced threads, ability scrolls and kage rares would not hurt much...

Yea they really need to update that shop. I guess its not bad that I'm collecting seal and summon scrolls from there but there could be much better options. Adv refines would be amazing.
