Lately there was a new update to insane bolt to where it became a triple strike storm damage instead of the usual single moon damage type. The new spell change is wonderful for pvp storms but is bit upsetting for pve mains. My suggestion is maybe have both types of bolts in the game and rename the triple strike damage one to Bolt Frenzy but make the previous version of insane bolt but make it No Pvp. That way pvp players now have access to a storm shield breaker spell while pve players can still enjoy having multiple copies of insane Without it effecting in pvp.
(and maybe change the chance of insane to 50/50 instead of 80/20 if you feel it is still unfair)
