I've been following Wildstar lately (no Beta
) and I think they have the right idea IF AND ONLY IF raiding is one option, but not THE option. The problem with WoW and MMOs like it (and I presume, EQ but I didn't play EQ) is that they push raiding as the pinnacle. The game is ABOUT raiding, everything else is a stepping stone/time waster to get to the current level cap and start to raid. All the WoW clones and WoW imitations follow this pattern: Leveling content is there just because you don't want to make everyone max level immediately, but the raids are what matters.
From what I've read WildStar plans to have various endgame content: Solo content, small group content, group content (i.e. like 5-mans), and raid content but I believe they're all meant to be on the same level, unlike WoW where solo < small group < group < raid. A better analogy might be how The Secret World handles their endgame (from what I've read, I'm only in the second zone): While it's focused around group play, the high level dungeons and the raids are the same level, the raids aren't higher and therefore the "real" endgame.
WildStar is doing something closer to that model. I think WoW COULD pull something like that off (I've said in other similar posts they could in theory make Challenge Mode dungeons drop gear, and then remove huge raids in favor of smaller multiple raids that drop the same level of gear, perhaps obscure things like trinkets or weapons or rings, as the revised CM Dungeons) but I don't think they would succeed because for all these years now they've perpetuated the idea that raiding should be the championship game, the olympics, whatever analogy you want, that everyone in an ideal world would be striving for.
