Game was in development since 2011 (as far as we know, could’ve been started even earlier)
Who knows how old their stuff is. Can’t really judge it by 2016 standards, unless they openly go and say that they are using the latest and greatest technology for the game. Which I highly doubt they are.
All we can hope for is a major overhaul in the future that will update everything. A lot of games do that.
Monk is a versatile class, that’s why you feel like it doesn’t belong anywhere. It doesn’t shine at anything in particular, but it can fill almost any role. It’s a unique strength.
Wugushi is my favorite archer class and if they changed/removed it, whole archer tree would be meaningless to me. On a side note, they need to add more DoT classes like Wugushi in my opinion, it’s a playstyle that I enjoy.
As far as I’m concerned, they are unique classes that aren’t for everyone. It doesn’t mean they need to be changed.
