People use Qilins like Ifrits while fighting cartels except it's solo pushes and makes fights last 30 minutes. The old meta was Ifrit drops and slams on windows or banana at OG. At OG Mushroom, people would use ifrits to push from South Rocks to South Tower or from North Forest to Dock tower. Essentially old school and traditional cartel fighters want Qilins gone because they turned fights into boring single man pushes.
Not to mention that Qilins are hard to shoot through and are exceptional while driving off-road.
