What I mean is this: wouldn't the article's suggestion imply a paradigm shift in all levels, not just the highest? I'm all for minimizing combat and putting an emphasys on the creative use of abilities, after all, Portal was a pretty good game.
The difference between "creative use of abilities" at high levels and at low levels, is that at low levels, when you choose to use an ability, you're taking a risk. You're not a demigod. You might fail. You're probably sacrificing another option by choosing to specialize in that ability. That depth is usually lost at high levels.
Eh, not if the high levels are managed well, as suggested in the article. A bad choice can hurt you in many different ways. Yeah, high level has spells like resurrection, wishes and other stuff that can make recovering from death and dismemberment not only possible, but trivial. But on the other hand, there are new dangers from which these might not help. Having your soul stolen, losing your fortress, having half of your army killed, spending hundreds of thousands of golden pieces in a wild goose chase.
These things can make stuff for which the players fought along while simply disappear. And while people point to the wish spell as if it was some kind of panacea, if we are talking about old school D&D here, wishes can bite you in the ass. In fact, they can be far worse than the situation you are trying to remedy. One particularly memorable case I remember was of a player unused to making wishes who tried to recover the soul of a PC of another player. He went something like "I wish I had Sir Henry's soul". So, of course, his soul was swapped with Sir Henry's (by the way, I made up this name, I don't remember the name of the original character). Sir Henry's mind now resided in the bard's body, and the bard's soul was now lost. Point here is that those cool weapons of high level can be dangerous. They may, and should, have unintended side effects.
