So I think the biggest flaw with sod is an inconsistency in “love” to the different specs and classes.
I started off as priest and healing is a straight rip from wotlk and shadow is subzero tier. Not a fun class in sod and not a class with a clear vision for how the runes were going to give the class sometime special.
I just started rogue and it’s abundantly clear how much thought was put into the runes to create a new experience. Specifically quick draw ranged kidney and saber. These alters the class in a way that still feels like a rogue but has something fresh.
I think the community should be open and vocal about the direction of the classes so that in the long run, most classes feel as successful as the pirate rogue
