Chainline from rear to front can give the optical illusion of a wonky derailleur in the extreme gears, so double check by sighting derailleur & cassette from above. "Normal" SRAM derailleur geometry has a very clear outward angle when viewed from both behind and above, on both vertical and longitudinal axes, on the high gears (small sprockets), neutralising & then twisting the other way as it shifts inward.
Due to the tight spacing of 12-sp, Eagle is very sensitive to tuning, so any tiny misalignment will make itself known with rough running & poor shifting. If it's not rattling when holding any given gear, and shifting smoothly both ways, it's most likely fine (apart fom being SRAM....).
