Celt, I'm going to agree and disagree with you on some points.
First off, if you post an opinionated view on a subject, you are going to get argument. If you want to just vent, you can write that on a piece of paper and put it on a shelf. Further, when you reply to those same people arguing with you, voicing further points you in fact continue the argument. I personally don't have a problem with people submitting a thread stating why they dislike 4e. Afterall, the boards are here to get viewpoints. But if your going to give your reasons you have to stand with them, and take all the heat that brings.
Alright, now that I've jumped off my soapbox, let's get down to your points.
I think you have some valid points with the wizard. Personally my biggest beef right there is that some rituals take too long and cost way too much. If a wizard wants to cast a floating disk, then have it take a 20 seconds, not 10 minutes. That's still plenty of time to ensure it doesn't have some quick broken combat use, but the wizard still looks cool as opposed to busting out the big book and singing kumbiya for 10 minutes. I think if rituals become a little more useful and more plentiful, that will give the wizard more "wizardly" flavor.
While yes other classes can do rituals, they don't have the innate arcane training, nor the high int, nor the free rituals. They will never be what the wizard is.
To your point on game balance hindering on immersion, I can also agree a little here. Balance to me is actually a very very important concept, I kneel down to the altar of game balance. However, I recognize there are many ways to do that, and some have more game immersion than others. For example, my own personal hatred on this subject is focused on the rogue's weapon restrictions. It really bugs me that rogue's have to use light blades and handcrossbows to use any of their powers. If a rogue spends a feat to get a better weapon, he should be able to use it. And the fact you can't sneak attack with a bow but you can with a crossbow? Come on!!
However, I think you contradict yourself when you talk about encounter powers...and then monster recharges. You said yourself that you think its stupid that a fighter uses a power than has to rest 5 minutes to get it back.
Yet that's exactly what the recharge rules push against!! It allows a monster to use a big move, and then after a few seconds of recovery can use it again. If you used that with a fighter, it would be the equivalent of the fighter pulling out his big attack, and then needed a few seconds of breathing room to use it again...which makes perfect flavor sense to me.
Overall I'm still positive about 4e, but I definitely think it has its flaws (see my threads about skill challenges if you don't believe me).
To me right now 4e is about a new framework, and what the potential for that holds. 3e has had a good run, but has shown some wear over the years. It has problems you can't solve with a quick fix. 4e has problems, the question becomes whether those problems can be solved with subtle additions as the game goes on, or if larger cracks will be found in the end.
Time will tell.
