Aura slot had a perfect purpose. Only problem was acquisition and cooldowns.

Why cant we just simplify the aura system by leaving the slot alone, removing a couple of the unused auras, making all of them available via gameplay, and removing the cooldowns.

Aura slot gives an option for players for different playstyles. Removing friction from using the slot and creating a strong permanent unlock that can be used whenever would be way better than whatever this blog is.

Stop trying to reinvent the wheel and solve the actual problems players have with the systems.
