Should also note that it really is a no brainer that the best gear is obviously going to be reserved for completion of the most challenging content. Whilst I do think there should be more variation in gear I don't think that people should get raid level gear without actually doing raid level content.

As for your point on letting raid gear be sold on the marketboard, again sort of removes part of the incentive to raid if just any shmoe could buy the gear plus it also would add additional temptations for people to give in to RMT.

In short if you want the best gear you have to do the content that drops it, if you're a person who thinks that it should just come to you without any real effort on your part then well....that's not really gonna happen.
