I am going to chime in on a reevalution of the Reign of Ice and Fire. The lack of cooldown probably needed to be changed when coupled with its damage, but I want to say that firing a lot of missiles was fun and to me was the core of the item.
So while there are a lot of ways to fix up the rings to keep them from being as underwhelming as they are now while keeping the 2 second cooldown, I’d like to put in a vote for a .5 second cooldown change. I would even be happy to take a .5 second cooldown change coupled with a nerf to damage values.
In short, the ring making an aura of swirly missiles around me was fun. I’d like to see that back even if it comes with a nerf from current respectable damage to the tickle like damage of a similar item, the Mythical Cortosian Scrolls.
