head to head
Borderlands 2 asks more than Diablo Immortal, and the gap is execution.

Optimization · Systems & Chaos
Loot-shooter RPG built on gear chasing.

Optimization · Systems & Chaos
Blizzard's mobile Diablo where loot RNG and paid gem systems drive character power.
Borderlands 2 leans Optimization (Systems & Chaos); Diablo Immortal leans Optimization (Systems & Chaos).
Borderlands 2 leans clearly harder on execution.
Borderlands 2
Aim matters but generous hit feel
Diablo Immortal
Touch-friendly combat with dodge timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Borderlands 2
Enemies are scripted loot fodder
Diablo Immortal
PvP battlegrounds exist but gear usually decides
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Borderlands 2
Procedurally generated weapon drops vary
Diablo Immortal
Legendary gem and loot RNG, heavily monetized
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Borderlands 2
Skill trees and gear math heavily solved
Diablo Immortal
Resonance, paragon, set optimization dominate power
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
