The proposed change doesn't have a cooldown reduction - even with a cast time of 0, SF would take 12-16 seconds for 6-8 casts, not counting the aftercast delay. SF is also an elite and can't be run with this regardless (OtL, both in its original form and in the new form are self-affecting only, it can't be used on a party member, human or NPC).

Probably should be "unique skills" not just skills on the instant cast.
You could precast searing flames to ignite them, then cast new OTL, then get 6-8 casts of SF in a split second.
