Regarding:
A small change suggested by Luka on discord (@Luka#8022 on Discord, @12thPower here on the forums).
Change Fiery Embrace to a single slot 50+5 Recharge IO.
Slot Fusion with Gausian ToHit/Rech, Rech/End and Build up Proc.
Fiery embrace will now be exactly double the recharge of Fusion so you can line them up to use together every other rotation. While this was specific to the Rad Melee build all of the standard build up powers should be 90 second CD by default (this will not work for rage or any of the other unusual ones) so this change should be universal across the /Fiery Aura builds and gives you a floating slot that you can do what you like with. Adding the Numina Proc to Health on the Rad build was one suggested possibility.
This was a great suggestion and adds a nice little bit of flexibility to those who like to make sure cooldowns all line up nicely!
How does one move one slot out of Fiery Embrace, and then add 2 more slots to Fusion, and still end up with an extra slot?
