I've stopped watching since around 2015(aside from a few youtube clips here and there because I liked a few wrestlers who stuck around since that year), so I have some questions as a test of quality.
Who are the top guys in this current decade aside from Roman Reigns?
What is the current top storyline?
Also has the women's division grown, improved, and have actual standout household name stars aside from Sasha Banks(and maybe Asuka) in the last 5-10 years?
I'll let you catch up on the last decade on your own my friend. Ain't no one got time to rehash ten years.
Current top storyline in any promotion is, hands down, the Bloodline. While you were gone Roman finally turned heel, called himself his family's tribal chief, and leaned into his family's history in the business. Then he added Paul Heyman as his "wise man" (instead of advocate or manager). This is not the pushed for the hell of it Roman any more. His storyline is killing it. And most of the wrestling world is waiting to see if The Rock will decide to throw his hat in the ring as head of the table in their family. If that happens the WrestleMania match will be bananas.
Women's division has also grown tremendously. Enough they get main event placement fairly often. Too many to mention right now between the two companies except for Dr. Britt Baker in AEW. She's a real life dentist, not a Kane one. And she kills it on the mic and has brutal matches. Also easy on the eyes. No doubt some kid is dreaming of having her knock his teeth out and put them back in after.
