So, after skipping an expansion I came back to WoW, and decided to start all new characters. I have to say, that after hitting level 30, I feel like there's almost no progress what-so-ever in levelling, and I've almost already lost my motivation.
I really loved the talent tree. I don't even care that some of the abilities were fluff, they were a necessary evil to get to better stuff, and it made levelling matter. The new talents, well, to me they just feel "meh".
Also, that you get skill "ranks" automatically instead of buying them. Well, on one hand I think it's great, and on the other hand it's yet another thing that's been removed to make levelling feel worthless. I think a great alternative would have been for a "You've levelled, congratulations!" window to appear, where it says which of your attacks have been buffed etc.
tldr; I think that the casual-ification is killing wow.
Oh well. Just a note from a player who gave wow another go, but is finding it hard to keep interested in levelling.
