Yes, everything has lost its uniqueness on the forums but what can you expect I guess. Because there will be that one certain person who likes that one ability or that one technique or that one summon but hates that character and wants their custom character to have it. I mean for the longest time my custom character had an Eternal Mangekyou Sharingan and no one truly had a problem with me having ice and the EMS but I had to drop one or the other with the bio rules and I dropped the Sharingan all together because I wanted to show people that you don't need a Doujutsu to be able to win a fight. Heck I have even shown that you don't need a "Mode" to beat someone else who is in a mode.
But yes everything has lost its uniqueness but what can you expect? people to say oh sure alright since there are this many of this I wont have that even though thats their favorite aspect of a clan, character, or anything?
Heck if we were going with the rules of Naruto there would only be Madara's and Sasuke's for Uchiha's, Hinata Neji and the others for Byakugan, etc. But this is what makes us so unique we have millions of uchiha's and byakugan users rin'negan users are popping up but only as Pain or Nagato or the Sage of the Six Paths.
As for KG's, Summons, and other things like that yes I would like to see how people have that as I put in my characters bio Zanji's bio that his grandmother was the head of the Hidden Snow and the KG passed on threw her daughter then onto Zanji.
All I request is that members don't only choose to have sth just because they saw someone use it and kicked a* with it because thats what kills it. For summons if you have the same summon dont even try to use the same summoning tech people should have their own. Because I have seen members go from not having a certain technique then once they saw someone use it or use a certain KG that person went and made a bio stating they have that technique which purely kills that techniques unique ability
