chain reaction seems to only do a consistent 3x explosions at a specific timing, regardless of whether or not I was able to re-cast the spell before the 3rd one had hit, I don't get faster or more explosions for the given time frame. This seems to be tremendously wasteful.
Instead, I've been using Meteor Shower and can hit this spell and have tremendous amounts of meteors rain on my area causing (what I can only assume) is more damage in a shorter amount of time. though it does eat through more mana, which isn't really an issue with mana returns on crit procs.
Anybody tell me if I'm right? or is there a mechanic with Explosive blast that makes it better?
