While it’s a strong combo, in practice it’s just a more clunky version of what a lot of other frames can already accomplish with subsumed Roar and their own abilities. An unmoddable 25sec of downtime that can only be reduced by killing 25 things without your strongest buff active is not very impressive.
Refresh rate is king. I would much rather use a 1080p 120+Hz monitor over 4k 60Hz. 1440p 144Hz is the sweet spot though, big visual improvement over 1080p without the need to bankrupt yourself on a GPU powerful enough to drive a 4k 120Hz display or relying on upscaling making everything a blurry mess.
