I'm enjoying it. I'm playing a single account atm, not willing to jump into boxing this early. I have a level 50 cleric, and have done maybe half a dozen level 50 dungeons.

Compared to current WoW, it's missing a lot. Compared to classic WoW or any other just released game, it's got a lot to do and is very polished. At 50 there are a couple normal dungeons, and two tiers of expert dungeons (WoW heroics.) The t2 dungeons are kind of like ToC/ICC heroics vs the standard ones. The blues in T2 are about the same as the epics in T1. The 'gate' to T2 is your hit rating. 1 hit rating = 0.2% chance to hit and you need 100 rating to get 100% hit for T2 (so if you have 0, you have a 20% miss rate.) For raids, you need 200 (40% miss with 0.) I like this gating system better, as you don't need to put obscene amounts of rating on gear and you don't need to make npcs hit 10x harder and have 10x the life in each tier.

The Rift system was amazing at first, now I don't really care for them much. They're a nice break from questing when one spawns near you, and the blue/epic tokens you can get during an invasion can buy some decent gear, but at 50 there's no point doing any but the 5-man/raid rifts.

Dailies, rep grinding, instance farming for tokens for gear, all the same in Rift as WoW (except there's no cap the number of dailies you can do.)

At this point I think for myself (and many others) that we're simply MMO'd out. It's not that Rift is bad, it's just that it's another MMO. I can farm gold/achievements/gear/etc in WoW or Rift, and the only reason I know I'll go back to WoW is simply because I have more time invested in it and feel more attached to it. Rift is a great game, and if I wasn't playing WoW I would definitely be in Rift full-time.
