Honestly SKB is one of WOW’s more difficult play styles not because its complex, but because of the unique off the GCD nature of fire mage and fire blast. Fire mage plays twice as fast as most of the game because it constantly plays between the GCDs. Once you master the between the GCDs problems, all versions of fire kind of become easy imo.
Even in Nyalotha with a very simple fire mage rotation, the difference between a good and great fire mage was very large. While yes, UI is mechanically easier to perform, it brings on new challenges that SKB simply doesn’t have to deal with imo.
In its current form, I would tune UI to be equal in single target to SKB. This imo works because SKB has access to flamestrike and more numerous pug friendly burst timings; this will ensure it’s place in the meta and game. Their niches allow them to be tuned similarly imo.
Can we also mention the fact that the only reason we are at the bottom right now, is because we had 5 back to back nerfs right after the rework? THEY thought mages where overpowered when in reality, the only culprit was the aug evoker. they just had this urgent feeling to “nerf the god comp” and that’s why we stand here today. It would be great to have a change to UI I agree, but before all I’d want a better balance between the 3 specs.
