The "Vince wouldn't buy out the top stars" thing is true but as you've then gone into that's no excuse for burying what you've got and making the Dudley Boyz some.of the top Alliance stars at Invasion or Shane McFuckingMahon one of the key parts of their Survivor Series team, or never once trying to make the WCW champion look a big deal, etc.
Make Booker T look like a killer heel, not some fluky jobber who needs Shane's help. Don't have WCWs babyface be a creepy cuck heel who gets battered by Sara. When RVD gets super over just make him a more central cog in the story.
But then as we've all long suspected and had conclusively proven over the last month or so, Vince for a long time made booking wrestling seem a lot harder than it is.
