Absolutely not. Wade is one of the best shooting guards ever. Even without being an average shooter from deep he was elite inside the arc and a phenomenal defender. Was the best player on the Heat's first title team. Pierce is a legit HoF guy, but there's a big gap between the two.
What does that have to do with anything? The Celtics formed a super team, just like the Heat did. So did the Lakers around that time. Does nobody remember the SI cover?
Your basis that the Heat were "better" (which is true) doesn't matter. Both Big 3's were formed with 3 hall of famers. Boston traded for theirs, while the Heat had to make a bunch of trades as well (including the two sign & trades) to make them work under the salary cap. You wanna argue it killed parity? Fine. But you know what really killed parity? Kevin fvcking Durant signing with a team that had won 73 games the year prior.
