Scripts/Eye of Eternity: Rewrite Arcane Barrage mechanic

* Note that even after last changes happens I'm not sure exactly how the timers are controlled. The wipe chance should be a lot smaller now.. Any further change I can think of is beyond what I see. The main problem is currently. In theory there is chance, If timers get to be same with delay lesser than 2 seconds and if target randomisations select same target for shit out of luck reason. And if starting different timers were matching you can be hit atleast 2-3 times and on 25 mode maybe more. The timers are not with fixed difference for sure is all I know.
