I hated 4e encounter powers and the idea that they are going to stick them on the wizard is downright repulsive. If they want encounter powers, they need to stick them on a class that makes sense.
Yeah, man, wouldn't that be ridiculous? For a totally made up, fantasy magical system? I mean,
everyone knows that magic works a certain way, and that anyone who imagines magic to work
another way is just out of their mind! Regaining spells after five minutes just doesn't make sense! That's just not how magic works!
That's what this argument sounds like.
First, repulsive? If you are so attached to a certain implementation of a made up fantasy system that a deviation from that causes you to bust out the word "repulsive," take a step back. Consider that maybe there are better things to be repulsed by, and that this probably isn't worth registering more than a "mild distaste" on your hate-o-meter.
Second, magic doesn't make sense. It's magic. It doesn't exist. Someone made it up. Along with everything that it entails. The idea of resting a day to recover spells? Someone made that up. There's no "sense" to it. The guy thought, "Hey, I want to make magic exhausting, so I'll require a night's rest to get it back." He could just as easily have said, "Hey, I want to make magic exhausting, so I'll require a short rest to recover it." Attacking encounter-based powers on an "It doesn't make sense!" level doesn't make sense. Ultimately, it's just aesthetics.
