I personally don't mind if people have stacked squads, especially when most (if not all) of their players are favorites of theirs.
I can see why it would be annoying to a lot of the more casual fans, but those players always seem to want to win straight away without figuring the game out or building up a decent team. As long as they're losing it's someone else's or something else's fault.
Having all of the "best" players doesn't guarantee a win anyway. It's which players work best for you and your team and how you use them. Personally, I use a lot of ball movement to create space for my shooters. When that's not working out I'll run a lot of Pick and Roll or throw the ball into my bigs. This method has allowed me to go undefeated so far in Road to the Playoffs. Several of those wins include some mega cheesers who gave me a scare.
Your quote about people not being able to have a Gold squad in a short amount of time without spending money on VC hits the nail on the head. This is about money.
What does it matter if people have "super teams" now or a couple months down the road? Most people who play to win will use their best assets. In this case it happens to be Gold players. Gold players, however, don't guarantee you victory because you still need a good amount of skill.
If MyTeam wasn't setup to encourage people to buy VC why are the packs so much? Why do we get so many duplicate cards? Hell, WHY the heck ARE there duplicate cards? Why are the "payouts" so small for each win? Why do we only receive a few Sapphire cards (they're really no better than their Gold counterparts) for winning Road to the Playoffs? And WHY THE HELL DO WE GET NOTHING AFTER BECOMING A FIRST SEED? It's all setup to encourage the "average" player to buy VC so they can "compete" because no one's ego can handle losing.
All I know is that Domination Mode was FUN. It was FUN unlocking all of those card packs and unlocking new cards to add to my collection. This "fix" takes away my FUN! Sure, some people weren't having as much fun because they lost, but those same guys would be complaining about something else because they'd still be losing.
