At the end of the day, the first three rounds of the playoffs are just a way to funnel one team from each conference to the finals. It doesn't really matter how you do it since there's only one winner anyway. I get that it's quite anti-climactic when conference finals don't seem very competitive, but we're only looking for the one team that advances to the finals. I have trouble imagining a scheme where Florida doesn't end up on top in the east, so the funnel seems to be working just fine.
That said, I'm as bored of Florida-Tampa and Florida-Toronto as the next guy, but stale matchups are fundamentally a result of the same teams dominating their divisions and conferences year after year. No tinkering with the playoff format is going to change that.
