I think having more quests and weapon choices is essential I love the Ice weapons great stuff nice and hard to upgrade etc but putting them in quests and more variety would really be nice like we want to see Warglaive of Azzinoth in the list coz of its 450 haste or thunderfury u know the classic weapons and the attack speeds must be different 2.5 and 3.6 is just all the same Daggers would be nice if it was 2.1 or something like that I know you can transmogrify it, but its not the same so maby just look into that idea.
And definitely more World bosses Make them a lot harder as well CP is way too easy it seems.
