Firestorm mechanic

Hello everyone,

The gem states 'Maximum 3 Firestorms at a time'.

If you get a decent cast speed and use spell cascade support, you can cast second Firestorm before the first one actually hits the ground, therefor the first cast does no damage at all. So basically you can stand still, spam firestorm supported by spell cascade support and you are doing no damage at all. :)

If you use awakened spell cascade support, only 3 big meteors out of 5 actually hit.

Is this intended? I would assume that the cap applies to the 'second phase' of Firestorm, where the smaller meteors hit periodically. I don't expect all the firestorms to stack, but the hits to do actual damage if they are cast.

Thanks in advance for all the feedback.
