Understand why certain gear items have to be less accessible. Don't like it, but I get it.
A problem I do have is that some components could be a bit more farmable, and some of the challenge rewards could be less useless.
If the level cap goes up any further we'll need new challenge tiers with correspondingly powerful component drops. This would probably be the solution that's needed.
Obviously if that occurs, raids would need reworking to be appropriate for higher level players, along with loot.
