The power scaling feels weird. Overall things feel pretty inconsistent and I think that there have been too many tiers of humans. It's extremely difficult to understand how strong each person is supposed to be when the mc has defeated like 20 different tiers of humans (each time he fights a newly introduced bad guy) It seems like levels mean jack, too. There also isn't feats to compare. We've never seen the heavens accomplish anything meaningful so their power level is just a giant question mark. With the mc's stats alone he should be able to dumpster just about anyone, plus he has 2 op skills, the ability to modify his sword aura, overclock, his experience fighting humans, and his spirit the ice queen. The heavens just seem like stat sticks for the mc to aspire to. The archmage being compared to Juha in strength seems totally absurd, so I really don't know how the guildmaster came to that conclusion.
