I dont know how to prove, but sometimes my iniative is 0 when I get in a fight. I realize that in sage war sunday, I fought the same lvl 83 guy 3 times, in the first fight my passive barrier went last, and that's normal since I have high iniative than he has and everything went ok, but in the second time he barrier went last and all his ninjas moved faster than mine, that would be normal if he had lvled up his refines but he didnt do that, after that I fought someone way weaker than me, (I'm lvl 83 and the guy was lvl 65), and his ninjas was faster than mine, I realize that something was strange so I refreshed the game and I fought with the lvl 83 guy again, and I was faster than him this time again.
This would be ok if it happened only once, but it happened again today when I was doing convoy.
