In regards to the whole 'pointless fighting' thing, I mean... To be fair, both Mokou and Kaguya are in this RP. Pointless fights between these two should be expected, at the very least. Probably more.
That aside, Jhin and Kled/Skaarl are definitely not fit for this sort of setting. One (Jhin) is a serial killer that wants to kill things to make them beautiful, which means he'd be gunning for the PCs just as much as he would the enemies at hand, if any. He also hates Shen and Zed for robbing him of another 'work of art', which shows his fixation upon holding grudges. Oops, had to kill a guy he wanted to kill because of extenuating circumstances? Hitlist. Not particularly someone I'd want on the list of PCs, to be honest.
Kled is just batshit fucking crazy, though. Dude raves about mind weasels and invisible badgers, declares himself to have multiple titles in the Noxian military, and constantly talks about how he'll kill his team later (he's just killing the enemy team first). It's not even a matter of ham; dude will try to murder everything he sees, regardless of circumstance. Also, he chugs mushroom juice, which he even says gives him hallucinations and paranoia. Someone with that much instability is definitely not beneficial to an RP and would likely be put down the second he tries fo stab a 'tresspasser'. Which, granted, would take... A few minutes, tops? Probably less?
I read League lore. I listen to the VOs. All this is rooted in what Riot has put out. While they may be fun to play, they do not fot the scene this RP is trying to set... In my eyes, at least.
Just putting my two cents in.
