The only potential mitigating factor in Malakai's usage is that he does apparently have quite a nasty back injury which has been causing him problems for a while, alongside some mental health issues which may or may not be related to said injury. By the sounds of it he's going to be taking some time away from AEW regardless, so I hope he heals up and gets better. AEW's biggest issue is that almost everybody is floundering in largely meaningless feuds because the roster is simply too large. They're trying to rotate people in and out constantly, and it leads to a lack of cohesion when it comes to week-to-week storytelling. There is some good stuff going on - Jungle Boy and Christian has been a really solid feud so far. Julia Hart joining the House of Black was well told (but what was the point, really?), Wheeler Yuta was elevated in an excellent way, Starks and Hobbs was decent (what was up with Starks being squashed at All Out though?), they've obviously done a good job with Hook, Jade Cargill has been booked well, the Daniel Garcia/JES stuff is good, the rise of The Acclaimed has been great. But, then, look at the sheer amount of top talent that is fucking floundering, doing nothing...
Hangman - what happened here? Why is he slumming around with the Dark Order after being the fucking champion, the culmination of a multi-year storyline? It'd be like Stone Cold teaming up with Too Cool after losing the WWE title. Just pointless.
Penta and Rey Fenix - spinning their wheels for months now, if not years
Santana and Ortiz - as above... I'm not sure they've even held the tag titles? Which is ridiculous
Andrade - in no man's land
Miro - just returned, but as above. I know he's just returned, but could he not have been plugged into something more important than a random six man with the House of Black and Sting/Darby? Speaking of which...
Darby Allin - What do they even want to do with him? Is he just going to do random matches with Sting for the rest of his tenure?
Orange Cassidy - loses a lot nowadays, and alongside the Best Friends completely directionless
Wardlow - his big moment was overshadowed by the work/shoot MJF nonsense, and since then he's pretty much just been doing nothing of any real note
Ethan Page - this guy has all the tools, should be utilised much better. What happened to America's Top Team anyway? is that just scrapped now?
Ricky Starks - feels like he's been criminally underutilised. This guy is a star
I could go on, but simply put... there are far too many very talented people on the roster that have little hope of doing anything worthwhile as there simply isn't enough time to squeeze them all in.
Oh, another two things I'll add to AEW's problems...
1) the number of titles. It's utterly ridiculous. Practically everyone seems to have a belt, whether it be one recently created, other company's belts, an ROH belt, made up belts like the Team Taz one... if everyone has a title then no titles are special. There are far too many.
2) The integration of ROH has seriously hurt AEW as a program, and I even think NJPW to a lesser extent has had a longer-term detrimental impact. There are too many random wrestlers turning up to do brief matches or feuds, then disappearing again.
