Eye of Winter buff suggestions

Eye of Winter lacks DPS. At level 18, it only does 30 damage per projectile average. With two elemental surfaces, this would double it to 60 damage per projectile per 1 second cast.


Analysis
Comparing it to a level 18 Spark, it does about 1/6 the DPS...1/3 with two elemental surfaces. Spark does 10-181 damage per projectile with half the cast speed for 171 average (for the same time as a cast of Eye of Winter).

Further, Spark would fire 32 projectiles for each Eye of Winter cast. The eye of Winter looks to shoot out 8 projectiles 5 times for a total of 40. However the Spark projectiles have a free ricochet support as they bounce off of walls, where Eye of Winter has 2.33x crit chance presuming max stacks of Critical Weakness.


Damage change suggestion
Eye of Winter could easily have the damage per projectile tripled. This would be a safe start, since this would still leave the DPS behind that of Spark due to the added damage from elemental surfaces not scaling with skills such as Archmage or Mana Tempest which 'gain' lightning damage, where the damage from elemental surfaces is also "gained". Not to mention the time used to cast other skills which create the ground effects needed to boost the damage.


Comment on projectiles
The amount of projectiles fired by Eye of Winter seems a bit anaemic, especially when compared to the old Frozen Orb from D2, but more projectiles would mess with the balance of stacking critical weakness and triggering crits.


Other issues
The detonation range is a bit short. Also it would be nice to have Eye of Winter detonate where the mouse cursor was when it was cast like Frozen Orb would do. Ideally the max distance for detonation could be near the edge of the screen.

Also the projectiles have issues with Pierce, and other projectile supports such as Ricochet. This bug further limits the potential of the skill.

Eye of Winter has weird interactions with Firewall as well. Only the fired projectiles gain damage from firewall - and only if they individually pass through it. It would be nice for it to either count as a burning surface, or for the "eye" of Eye of Winter to pass on the Firewall buff to all projectiles it shoots.

+1. Tried it out for a few maps and quickly switched. It feels like comet is the last tier cold spell. would be great to get eye of winter feeling OP

+1

I still use it together with knockback, but it definitely lacks damage.
