People. I find my number one problem in most editions is people.
I was playing a druid in 3E, and I took less time to take my turn than the Barbarian... [snip]
I wanted to kill him, and I like the guy.
Same bit in 4E. You have a handful of powers people, you don't need to read your character sheet EVERY TIME to figure out what they do.

Oh, I feel your pain. I play the wizard in our party, which means I need to keep an eye on where a dozen creatures (allies and enemies) are, what they're doing, what I can do to stuff up team bad guy as efficiently as possible, and what conditions I'm laying down and when they expire. And I take less time to decide what my character is doing than the players of the hexblade and the fighter - whose sole job it is to hit things.
And invariably I'm telling them not to move into my wizard's obvious blast areas - unless they want to be dazed and slowed and knocked prone too.
"But I can get a flank", they protest.
Dude, you're 15th level. If (a) you need a flank to get combat advantage; and (b) you need combat advantage to hit; you're doing something wrong. And so, in order to get a friggin' +2 bonus to your single attack roll, my wizard will forgo hitting 3 bad guys, doing 60+ points of damage, and imposing some condition on them which means you'll get combat advantage anyway?
And then, because I tell them it would be unwise to move into the square they had originally planned to, it takes them another 3 minutes to work out whether they want to move to a different square that's just next to the original square, and whether they now want to use a different power.
What's wrong with you? Ah yes, that'll be because your character has 9 Int, right? Role playing that Int very effectively aren't we? Pity, cos' when we actually need to role play, you sit there like a stunned mullet, or play on your phone...
