Better booking/writing, improve logic and continuity
Better performers, lots of guys just seem generic to me
Treat matches like they actually matter, call the action in ring instead of talking about other shyt, go over wrestlers' moves and discuss match strategies, shyt like that. I liked how Ventura, Monsoon and Heenan would call matches back in the day.
Make championships matter
Rebuild tag team division
Bring back some sort of cruiserweight/light heavyweight division
Let wrestlers go, get rid of scripted promos, let them sink or swim on thier own shyt
Bring back managers/valets
Less PPV's
Stop pandering to celebrities for mainstream media attention
Not really what 'wrestling' needs this is what I believe the WWE needs, I could add more but I think thats enough for now.
