Some people enjoy that style of play, others don't. Who can tell them what edition they can or can't use that play style with? It's really nobody's business but those around the table.
I think the arc of 4e has changed on this.
The 4e DMG infamously includes a bit where it tells you that talking to NPC's isn't fun. The idea of many of the rules were "basically handwave everything except combat, and get
very detailed on combat."
Mearls alludes to that with the "gnome problem:" when they first decided to ditch the gnome, they had found that only 10% of players even bother to play a gnome. They didn't think ditching the gnome would be a big deal, but they didn't imagine that the 10% of players translates into half of all gaming groups. Even a small percentage that wants something can affect a huge number of gaming groups.
That's part of what I see
Essentials as addressing: WotC isn't going to tell you that you have to play D&D in a particular way anymore, and Essentials is a toe in the water that says: "We want to support your campaign, whatever your campaign happens to want," rather than "We're going to make a game, and if you don't like it, you're wrong, and we don't want your money, and you can go play
Pathfinder."
They can't get every dollar back, but those they can get back, I imagine, they want to get back. And if all it takes is making a few marvelously effective builds without daily powers...well...that's really not even a big deal, since there is certainly more than one way to balance a class.
