Personally when I did play I would choose the fighter because I didn't want to think much. I mostly DM, and when I played I wanted simplicity. One of my problems with 4E is that now all of the classes are the mage. They all have powers and power management, and that turns me off. I haven't played enough to get a total picture of the game, but that is one thing that really irritates me.
I can totally get
that. I liked playing 3E Fighters for the same reason, and 3E Wizards for the opposite reason. (At higher levels though, Fighters did became a little more complex, once you'd account for buffs and debuffs... But that's nothin compared to managing a high level spell list)
But I somehow feel as if the complexity of 4E is in my "comfort zone" of complexity that I might be willing to enjoy a lot more than the more extreme spectrums of 3E. But of course, I have played 3E for 8 years, and 4E only a few months.
The OPs post, not so much.. not anymore. it is too much rehashing points(probably unintentionally) that I've heard way too often by now, and stuff I know how to deal with, even keeping my disbelief suspenders on.
And Minions are one of the best
inventions additions to the game. Every encounter gets better with Minions. (But then, I've seen Minions dropped like flies, and seen a horde of Minions taking down a Paladin, Minions that survived several attacks from the Wizard, and Minions that were dropped just because a Warlock looked funny at them...) I really love them.
Wading through hordes never worked better.
Dragons still kill entire hordes en masse. Just remember that "en masse" means Minions with some few lucky regular or elite guys that survive just as well as the occasionally missed Minion standing after the first wave. How often do we really see hordes dying with no survivor?
When I am thinking of a combat encounter, I like to think of it like a battle depicted in a movie. Encounter powers, Daily powers, all these stuff make perfect in a game. Of course the signature killing blow of the hero is only used only rarely (maybe more then once per 5 minutes, but I can narrate or visualize my actual game mechanical kills however I like, and when I want to use the signature killing blow image, I'll do that!)
Of course the Wizard doesn't cast his most powerful spells all day!
But be aware: I am a liker. After leaving Dark Knight, I found the movie just great. I couldn't name a single thing that bothered me. The friend I was watching it with pointed out the flaws first, and then went on to the praise. (Though I think he didn't have the reaction after "Das Parfum" (The Perfume?", the movie from Tom Twyker based on a book from Patrick Süßkind, so maybe there is stuff that can even blow his mind away

)
