As you know all flyers ability to pickup wild dino is disabled on PvE and it's only able to pick your own tames. When I asked for reason I heard things like "duh its PvE" or "to prevent taking alpha dino to someone base and destroy it". Later I checked wiki and realized they never had the ability to pick alphas. (not even alpha raptor) and exactly because "it's PvE" that we need the flyer to have this function (what other use does a Quetzal have other than picking wild dinos to move to traps in a safe place to assist your tames? There is no soaking in PvE and it's useless for farming (compared to argy that picks both anky and doedi and is much faster and easier to tame and breed, or you just use the skiff in endgame))
And we already have this rule: "Luring dinos to bases is forbidden (unless it is your own base)."
If someone wants to break it they don't need a Quetzal to do so.
