The wizard in our 4e game is stunningly ineffectual. I think the "Nerf wizards!" meme went way too far. We have a melee-heavy party (rogue, ranger, paladin, wizard, bard) and we are in an urban campaign, which means a lot of tight alleys, small rooms, and interior spaces. Slowing enemies doesn't work because the melee is rushing into range with them. Hindering terrain screws us up at well. Area spells catch us in the bargain. So, pretty much, he's limited to magic missile, or "Magic Missing", as it has become known.
Definitely needs a buff.
I think it's interesting that the "Controller" in 4e is supposed to be what most would call a Debuffer in an MMORPG. This is a very useful role in a group (my ranger Daily which weakens a foe is extremely effective), but the wizard, currently, doesn't cut it. Since they seem to know this, it will be interesting to see if it's "fixed" in Arcane Power. (Is that before or after PHB2?)
