Oohh! Haven't been playing with Naruto RPs for a long time with the obvious reasons at hand.
I'm in! I can also co-gm if you want.

The way all this trend is going leads me to believe with all the big group and stuff, I must say Magi The Kingdom of Magic reference? You know ever constant adventures instead of just staying in the leaf. TBH, it's nice going back and forth to the village but it eventually loses its appeal. Ninjas are smart enough IMO to have some form of mini HQ all over the world. Just a suggestion going by story in-universe.

WAN MO TING! *inserts Jackie Chan's Uncle voice* We are all aware of the following:

-Lesser Uchihas to the point nobody starts getting butthurt at each other or no Uchihas at all, lesser bs and at the very best they can only have their Base Sharingan with 3 tomoe and not MS.
-Power levels and characters. Let's be honest, nobody wants to spam Chakra Gundams, Rinnegan and cute tsundere tailed beasts or even have one inside their OC. If we go on the "Don't make your OC a Mary/Gary Stue" perspective, OC shouldn't be stronger than the canon characters and all that stuff. I do suggest you put some restrictions and standards on who gets to make the cut for Jounin because there's what you called "Room for improvement". 

Back to the power levels, I think I'm half right on that account. There are some instances that our OCs can be stronger than the canon ones. *Cough* like majority is basically > Sakura, Ino, Hinata etc. More so there's the gag thing that everybody who wants to make a prodigy makes a strong reference "Sasuke level" like wut.

WAN MO TING! (Yeah I had a lot of Jackie Chan Adventure lately but watevs xD) I think everybody should agree that Rper #1's character is/could be stronger than Rper #2's OC and so on. It would be too boring if everybody is at the same level cuz variety. There's such thing as "Kryptonite" because every jutsu has a weakness. Fairy Tail is the best example of portraying this with standard mages and dragon slayers of the same element. 

-Plot. I am honest here. For now yours is vague but I summed it up as "Big Adventures" from one point to the other. Traveling all over the world! 

-Characters. You're straightforward to begin with. Nobody wants a forced relationship *cough forced pairings like in the manga, don't attack me shiipers lol and Sasunaru*

You got my interest.
