Ice Knife and Witch Bolt as Cantrips?

[dmhelp]

Would witch bolt and ice knife be better as cantrips?

Ice knife would need to be reduced to 1d6/1d6 burst scaling.

Witch bolt still requires concertation.

Thoughts?

I wouldn't do ice knife because it is also area of effect. Witch bolt I think works ok if you drop the follow up damage.

I allow:

• Single target spells that spell (melee/ranged) attack may also be cast as cantrips (assuming they are known/prepared as a leveled spell) with the following base damage dice: chaos bolt d8 (loses leap, but can choose damage type from any of the d8s rolled), chromatic orb d8, guiding bolt d8, inflict wounds d10, melf's acid arrow d6 (still does 2d4 delayed hit and half miss damage), ray of sickness d4, witch bolt d12 (loses follow up damage/duration)

So witch bolt does superior damage vs firebolt, but is limited by the 30' range.
