the major thing that i like about 3e was that options were basically limitless and no matter what class you were you could do well with enough smarts
3E has billions of options. 99.9% of them suck. As in, "you are a danger to yourself and your party" mind-blowingly, awfully, uselessly bad.
As for the remaining .1%, 90% of that merely sucks. As in, "I'm a 20th level fighter, my friend is a wizard, so I was obsolete 10 levels ago. At least I don't have a cleric friend, so I wasn't obsolete 15 levels ago."
Now, 4E may have only thousands of options. But all of them are at least decent options. Foolish "traps" such as 3E Toughness, idiotic game-breaking legacy spells, and entire classes made redundant by the spellcasting system that a few of them got to play with? They're all gone. Now you can make a character concept that isn't useless without online research. If you want to make, say, an elf rogue multiclassed to infernal warlock, the optimizers may laugh at you, but you're not destroying your party. No more do I have to teach first time players to take X levels of scout and X levels of ranger plus plan out all their feats and spells so they keep up with the veteran players...I just say "You want to wield a bow? Then make a ranger. All the powers are good, take the ones you like, ask me if you have any questions."
In addition, the depth of 3E multiclassing has now given way to vastly more options within the same class. I could literally make Fighters all day.
