I'd counter that some cosmetics that modify skill graphics effects to precisely show their AoE are a little pay to win.

They show their AoE area to the enemies, so more like pay to lose. But you use them anyway because the effects are shiny.

Are you talking about the cosmetic for the Lina second spell ? Doesn't the cursor show the Stun range when you're about to cast it ? (the only broken cosmetic is the one that make Nyx Assassin look like Sand King)

That Mirana arrow is definitely pay to lose xD

Also Wind Ranger, Spectre, Disruptor, Pugna, Elder Titan, Medusa, Nature's Prophet, IO...
