“his alcoholism put him and everyone in danger he’s supposed to be the responsible adult yet has been throwing pissy fits since finding out the truth I’m getting real sick of his shit personally”
Gee it’s almost like Qrow’s undergoing a character arc where he;
Finally realizes how toxic his dependency on alcohol is and how it’s making even Ruby short-tempered at him, to say nothing of how it meant he couldn’t help when his nieces nearly died to the Apathy.
Regresses to the point of being a non-functioning alcoholic before being literally pulled from the brink- remember he was pissed at Weiss wasting the booze until he saw the Apathy and finally shook himself out of his stupor.
Starts to get over the not-insignificant realization that the man he saw as a surrogate father was basically making up a plan as he went along and has been keeping so many secrets close to the chest it’s hard to tell when he’s actually telling the truth anymore.
Also realizes as a consequence that Raven was right all along and that Salem was unbeatable, meaning he wasted the entire back half of his life on an unbeatable foe and that all his Huntsmen friends effectively died for nothing.
Qrow has been fighting the longest of the non-Wizard heroes right now and over the course of one horrifically long day, he’s had the wind taken from his sails multiple times thanks to Oz’s past lies and half-truths broiling to the surface, and once the party reached Brunswick tried to fall back to what he had tricked himself into thinking was his one solace- alcohol. But once it made him effectively invalid and made it so he was useless when his wards were nearly dying just feet away and him unable to do anything, it finally made him realize that his alcoholism was a crutch.
Qrow has seen a lot of shit and has developed a lot of bad coping mechanisms to help him sleep at night.
Will Qrow stop drinking entirely? Perhaps not, but I wouldn’t be surprised if down the line, Qrow tosses his flask away and we get a shot similar to the end of the Adam short, barring that Qrow’s more confident as he leaves his vices behind.
tldr, Qrow’s had good reasons for falling into his alcoholism as far as he did, you’re just salty that he’s being depicted realistically now.
(also can I just say as someone with alcoholic family members it’s very clear that some of the writers have some too and knew exactly how to write Qrow as a consequence?)
