Let me be clear: I am not asking for a rathma nerf. If anything It needs a buff instead. Rats is just the term most people use when what they and I really mean is the Legacy of dreams version of the build. It has been & still is clearly outperforming anything else for years now!
The singularity rune on the mage skill itself indeed has a very similar mechanic to the Bazooka wizard. You spent all your resource to create an insanely powerful attack or in this chase auto-aiming minion.
Even with all that it doesn’t necessarily need a nerf just other classes should be brought up to speed and not cripple behind 10 greater rift tiers like the vyr wizard does after the nerf.
