At the risk of sounding like an old-school DM (which, technically, I am ), this assumes that the PCs are expected to win every fight.Yeah, but it only works for a while. I haveDMed 4e for a while and would still DM it, if I had the time. I know, that you can make it a bit harder and a bit easier. But from a player point of view, with DM background, I think most combats are absolutely boring. I know that all fights need to be balanced, as I have only 1 daily to fall back on, if the encounter is harder. And this daily is only borderline more powerful than an at-will. It is like standing there, doing the same things over and over again.
The presence of multiple, strong daily powers does relax this assumption, but only because the DM feels more comfortable including stronger opponents which the PCs can defeat through the use of multiple, strong daily powers. If the PCs have already used those powers at the start of the encounter, however, then there is a good chance that the encounter will not end well for the PCs.
However, you don't need multiple, strong daily powers to relax that assumption. The PCs could simply pick their fights more carefully. Or, they can adopt "combat as war" strategies to even the odds if they realize they will be outclassed - using guerilla tactics to wear down large groups of enemies, a little at a time, for example, or weakening a single, strong enemy through traps or poison, or by exploiting a vulnerability. This can be done even if the party consists of nothing but pre-4e fighers and rogues who have no encounter or daily abilities whatsoever!
