Actually, now I get it.

ATK and DEF rise at pretty much the same rate. They cancel each other out, so the damage dealt will always be the same no matter the level.

Meanwhile, HP grows like normal in its side. To put it simply, the higher the level, the longer the battles will last, even at the same level. Let's compare with Rev vs Rev again.

(127/59) * 8 = 17 Damage (22% of Rev's Health) (Level 10)

(127/59) * 8 = 17 Damage (Nearly 4% of Rev's Health) (Level 100)
