The reason that wizard and the other caster classes were given new skills is that rogues are DESTROYING THEM. The rogue specs were to overpowered compared to the caster specs so the caster specs got a buff. Also wizard was given this skill because root is the weakest slow in the game (breaks on damage to the caster or the player) and the warmup on bolt was significantly increased (now 1.5seconds). This will not turn into run, root/icebolt, bolt, run because bolt is an extremely easy thing to counter especially now that the opponent has another .5 seconds to block the skill with a bash or a kick. This .5 seconds does not sound like a long time, but trust me it makes a massive difference. (sidenote wizard fireball got nerfed hard, 30 damage/fireball lost) In conclusion don't piss ur pants at this sight of this skill it will change how wizard is played but will not make it OP because it is no a guaranteed slow, the person needs to be able to aim the icebolt the same way they do a fireball.
