I voted both, although the poll has terrible options and deserves any vote stuffing it gets.
I'm like a lot of people in that when 4e came out after a brief time myself and everyone I know switched systems and never came back.
We actually started and ran a 3e campaign as a kind of send off an preperation for 4e coming out. The DM had a terrible time because no matter how hard we tried to play in good faith, the system kept jumping up in our faces and doing dumb stuff. We all had to put up with it but it was hardest for him because he had to do prep.
But the end of that game we had an army of undead, all my paladin ever did in combat was drop his shield to vaguely tweak his tactics, and the most fun we had was watch the druid and his adorable allyosaurus rampage around the place.
The DM would set up huge important fights and get them knocked over in a round, and then toss some side-monsters at us in a sandboxy session and almost kill us all. None of which he ever planned, because CR is garbage.
And CR was just one problem. Name the mechanic, it popped up and mocked us for playing 3e. CR. Sepllcasters vs nonspellcaster. Undead, pets, and followers- even after we houseruled them. Killer spells. Save or die spells. Having to recalc stuff five times in a round. Chrisma tree treasure. Level frikking drain.
This was not intentional by us. But the more we played, and the more info came out about 4e, the more overwhelming and obvious it became.
Now we play 4e and we're much happier. That was a clear improvement for us. And yes, we roleplay all the damn time, and 4e only made that easier because we all have more time to spend on it, because we aren't sitting around trying to figure out which layer of our defensive items just to disjoined.
Unfortunatly, this poll doesn't allow for people like us, quite clearly it's only interest is to emphasise how many people don't play 4e, without giving fair voice to the counterpoint- people who switched and never looked back.
