no it isn't, FAR from it, in fact, it is my belief that 4e give the characters WAY LESS license that every before
I have never had that problem, usually at my table, the players never want to bypass anything, if the DM says, ok, blah blah blah this is the adventure, and the players say we teleport away, thats a whole night wasted...who wants that?
I think it is kind of a shame that all your players want to do is be the uberest they can be, and I guess I am lucky that my table is full of players who like to role play.
The key distinction is 'in battle' vs 'out of battle' narrative control. In previous editions players had way more out of battle narrative control in that they had much greater ability to determine which fights they fought and under what conditions. Of course players had some abilities they could use to force monsters to do what they want in battle, such as charm or even tripping or grappling, but as we all know that very rarely happened due to the cumbersomeness of the rules for some of those abilities, or the difficulty in beating a decent monster's saving throws for others.
In 4e on the other hand players have a lower ability to control what fights they get into and under what conditions because their out-of-battle spell casting has been slowed down and toned down to a large degree compared to 3.x. However, players have a greater ability to control monsters within the battles themselves thanks to dailies and encounters that all classes have access to that stun, knock down, or force movement on monsters automatically, no matter what monster it is, even on a miss.
BTW, I'm glad that your players are perfect, my players are perfect too, but that has nothing to do with the actual nature of the rules as written, which is what we are talking about.
