Given the groundwork and "idea" of the game, I just dont see how they can get away from the "gamey" feel if they dont want to utilize instancing, dailies/weeklies, etc. that people say "ruined" WoW.
That Bone Construct "Cage" is just one example of what theyre working on and for that encounter, it seems fine for what it is. If anything, I think they should add more flare to that one encounter - like the group that "triggers" the event stabs the ground and a shield goes around group members, stunning them for a brief second - while the bone construct spawns, slams the ground, and everyone thats not in that bubble or w/e is grav fluxed out of the room. Presentation and all that.
Same with the raid boss that spawns in a sand storm. The group that triggers that boss makes an action of "hunkering" down in the sand storm, and everyone outside of that group is "feared" with blinding sand on their screen and they run to the perimeter of a "sand storm wall" before the fear ends. Unable to get back past that sand storm wall until the encounter is over.
Just two examples that come fresh to my mind with the limited bit that I experienced before stepping away from the game.
I dont necessarily understand what hes getting at, or trying to elaborate on.. with boss encounters being able to spawn every 15 minutes for example. But again, I'm not against most of the changes Ive seen taking place when it comes to raid bosses. Gamey or not.
