Syldor very well explained how the system working except some parts like you can see players level (main character) and mission rank. Is the system fair , balanced ? No its not. Is the support system useful? Somewhat yes but it has big flaws , its depending server , groups , probably its used mostly by f2p or lower level and battle power players so in that way -15c if you lose total nonsence 10 ignots for more ss mission also nonsence you need to use an other player team that you not familiar (short story i defeated 2 plunder whit sagenaruto that i dont have 5th kagegaara that i dont have azure fang i never ever tried out that main and whit ao the 3rd plunder defeated me when i constantly attacked , yes its annoying. Only "bright" side you can try out ninjas beside the arena even its not yours). Or you can camp and bully low levels as everybody else doing.
