Yes, and? 4E is terribad.
Well, it's not that bad, but it's still pretty bad.
So what's bad about it?
The main issue most people seem to have is that it's not literally just a reprint of 3.5
And that's fair. It's not. Compared to 3.5 it's barely even a roleplaying game. So little variety, the classes are are generic, no room for doing anything. It's more of a tactical combat simulator.
But in exchange for that you get far better balance and frankly most of the time I find the combat far more interesting in 4E.
It seems that 4E has lowered the amount of actual roleplaying in it, which is sorta fair and true. But to be honest 3.5 already had the systems needed to eliminate roleplaying, and I find that frankly, no matter what edition you are playing, the amount of roleplaying you are going to do is going to depend on the players and the GM of your group.
So yeah. That's how I see the difference between the two. Frankly, I do like 3.5 more, because it allows for more customization, and with a good group of players with good synergy I think that in most cases they will use the system to a better effect. However, in a less good group of players without synergy, I think 4E is superior. Coincidentally by the way, that second scenario is the one that exists in FG&RPing. So I'm a bit surprised that so many people around here don't like 4E, because it frankly feels like it would fit a majority of games on bay12 more then 3.5 (where you, sorry to say, have a lot of really unbalanced games with pretty spotty roleplay anyway where the GMs don't really seem to know what they are doing, issues that 4E addresses, or at least doesn't worsen.)
