If i remember correctly Flare and Ice Blast used to be fast-spamable 0 second cooldown skills. But for some reason they decided to give it a high cooldown and 2~3 overheats instead, which killed these skills. If we had these 0 cd spamable Flare/Iceblast with the damage improvements from the last patches these skills would actually be quite nice.
Flare for example, contrary to what many people think, does not require a target to have burning status from fireball or ignition. Standing in Flame Ground or Fire Pillar however also put targets on burning status, they just have a different-looking burning debuff symbol.
So if we had this 0 cd Flare we could mob 20+ monsters on a Fire Pillar, locking all of them them in place while burning them and then spamming 3~4k flare one or two times per second.
