I think it's an attempt at balance, not necessarily a shift of commitment. From what we have heard about Mod 9, it should be one of the largest content updates we have had:
- Level cap incrased by four levels
- new race(s)
- new raid
I certainly don't have a flawless memory of all of the updates, but I'm fairly certain that mod 8 was one of the few that had an overwhelming focus towards lower levels, at least on the order of magnitude of an entire new player experience, character creation menu, etc.
As far as your points:
4) There is certainly some luck involved in completing Dragontouched Armor, but it could also potentially involve just as much, if not more grinding than the Shroud. The randomness seems like an interesting attempt to get all players (as opposed to just casual or just power) to work on the mod 8 quests.
6) This is only a single quest. Were all of the mod 8 quests designed this way I would be more suspicious. It also seems to be in line with the changes to Reaver, Hound, VoD, etc. as an attempt to bring the quests more in-line with how they were originally envisioned.
7) Similar to #4, it could still potentially take some grinding, which a power gamer could accomplish (either by repeatedly running low level quests, or by just outright buying the ingredients) faster than a casual player.
12) This the point I disagree with the most. The monk class definitely favors powergamers over casual ones. They are significantly reliant on attributes, strongly favoring the player who has unlocked 32 point builds and has plenty of +6 stat items banked, as well as access to +2 tomes over the player who hasn't, doesn't, and doesn't. I would also argue that the monk class is more complex than most (even all) of the others. It requires some major twitch skills to perform well, which improve with lots and lots of practice. Keeping an entire party buffed with Walk of the Sun and Aligning the Heavens (maybe even Dance of Clouds - I think the names are correct, may be slightly off) is
NOT particularly easy or quick to learn how to do well.
I certainly hope that Turbine will continue to try and provide content for both casual gamers as well as power gamers, and it seems that that is there aim. We're just seeing one side of the coin right now, and it looks like it will flip for mod 9.
