I miss talent trees, what did they really achieve by removing them, not only in WoW but Diablo 3? I remember them doing several blogs how they wanted to remove "clutter" and what not.
Its not like we have more (or even less) options today, at least talent trees gave you the illusion that this was your own unique character and you had something to look forward to when you leveled and got that 1+ point to spend. It was progression, you had the entire "i just need to play a bit more to get my new talent point" kind of hook, now you just play and the game does the rest. Less choice for the player now after several expansions than people had a launch, that is very backwards.
There was nothing wrong with them, and ive never seen anyone complain about them. Now you just get abilities automatically and make a few choices towards your way to lvl 90.
