Issue #1, Dead Levels, I'm OK with seeing classes built so that they get something every level; fighter levels 5, 7, and 11 used to annoy me every time I played one. But with a caveat: I'm fine witn including levels 3,4,6,8,9,12,15,16,18 and 20 in the calculation, because you ARE getting something at those levels no matter what class you play; it's when the only thing you get is BAB, or hit dice, or more spells, that bugs me. And I don't think it should be as one class compared to another class; it should be as one class compared to all levels.
Issue #2, the "per-encounter" shift, I DEFINITELY don't like. I don't mind it as an option, but seeing it as the way all of D&D might go in a few years' time annoys me greatly.
Satori's example above:
"Gandalf save us from the Balrog!!".
"Sorry mate I used my high level spells against the Orc with class levels....your swords will have to do".
I'm not sure if I find it any less believable than Gandalf saying,
"Ask the Balrog to stop fighting us for six seconds! Then it'll be a new encounter!" In both cases, Gandalf needs to rest - but I'd believe it more as "tomorrow" than "one minute from now."

...And it would be nigh impossible to have the PCs have a dozen encounters in the day.
On the contrary, if clerics received their healing "per encounter" then we could well see some first level characters enter The Dungeon of Doom in the morning, and come out at 8pm that night at 10th character level! If people used to complain about someone unrealistically achieving ten levels in two weeks, I can only imagine the fits received at that kind of paradigm-shift. Site-based adventures would have to be radically altered, and encounter-driven adventures, where encounters are sparse, would have to be the norm.
If all of D&D changes to a "per-encounter" basis, XP awards will need to be shifted to "per session" than "per challenge" (say the PC's get 300 xp x level per game session or similar). Also, healing will have to be curtailed and most spells rewritten. Imagine regaining all a wizard's spells or cleric's heals and summons every time a fight broke out. They would have to be sharply curtailed in numbers available per encounter. Also, the definition of "encounter" would need to be rigidly defined even more than it is now; an "encounter" would be picking out a neighborhood stray dog and killing it, so it needs to be "one or more creatures intent on violence whose combined EL equals the average character level" or similar.
