I'm still disappointed that the content shown in their trailers before the release was missing and the changes made are actually downgrades.
There's still stuffs I like about D3 though. Joining of games created by friend, health globes, gold auto pick up, pets that proc, not need for mf/gf due to paragon.
But damn lots of things I missed, weapon swap, elemental weapon effect, other gems/jewel/runeword stones, useful white gears, aesthetically pleasant crystal swords etc
And some I really hate which is Huge Cooldown! Rest I rather not talk about it.
