“Why is Akira so high? His Ultra Talent is overpriced and his surge misses.”
Akira is high up because of his surge ultra talent granting him a whole new dynamic to his kit. His DPS is far more justifiable with this form of piercing damage, not to mention with stat talents he can rival the DPS of Ritual Saint Kasli/ Asukasli. He also has 2 powerful niches being alien and aku, having both strong and freeze against both. Lastly he has a wide array of qualities such as good survivability, strengthen, and wave immune. His overall stats and ability set are reminiscent of what you’d find near top 10/ top 15 ubers. His surge does not miss and we don't give a damn about investment cost.
“Why is Vigler so high?”
Combo.
“Why is Catman so high? He is old and generic, he should be lower.”
He’s adequately placed. The uber right below him, pre-UT Warlock, shares many similarities. Catman has the same role as Warlock but has higher stats against floating, angel, and alien (except when compared to Klay) while also having relic target, better survivability, and ability to hit other traits. In comparison to Warlock, Catman is a close rival and deserves his rank even if he’s a fairly old uber.
