Honestly, I'm not too sold on the idea that runescape even needed raids or that they're a good idea. So, even if they work perfectly they may still suck. We'll see how it goes though, low expectations for this may mean I'll enjoy it more than I did the World Event where although the islands were relatively creative I had expected so much more and that killed it for me. If you looked at how PVM progresses in other games, such as wow, you can see a complexity progression similar to how runescape has gone from monsters such as the KBD to the KQ, giant mole to GWD, nex to rots/vorago... I hope you get the point. Now I think jagex is putting in another layer of complexity using stages. For example vorago has several phases, but I think jagex wants to add stages where the boss and maybe the environment completely change - almost like a completely new boss encounter, but not...
