Steer away. Use the saved money for
I can see why having fun is difficult for you.
Here is simply what I think and why I don't recommend playing WOW too much nowdays.
Yeah. A lot of players including me lost more and more fun for every new expansion. Started getting more boring and more offline every time.
I simply support the level 60 community, and will consider returning if the known requests are getting heard for once. As i don't have fun in current wow, and therefor no reason to recommend it.
Not everyone sees it the same way, but many do.
( Not going to bring the whole list.)
I think it would be more worth the time if we had the abillity to know we can keep on doing what's fun even in the future.
Since some fatal expansion might show up and delete/ruin what's cool. I don't recommend investing too much time in this game as it is today.
One example is the weekly caps. Almost regardless of ratings or anything you'll still end up getting the exact same gear regardless how well you play or not. So I don't find any motivation to even put in a effort to earn gear. So where is the fun in a game when you're not even motivated by the game to put in any effort?
I also think it's sucks to invest too many hours on something you gonna be forced to change regardless what later because of expansions etc.
No need to bring any more examples here I guess, stuff should be clear.
Only recommendation, siimply avoid playing if you don't think it's fun. As I'm doing the same.
