It is. But that's not the biggest issue. It's the gear complexity.
They have AP, artifact trees, talent trees, PvP trees, lots of abilities and lots of complex gear options. I think they should make gearing up simpler. I don't think that even mythic raiders are very amused about how the stats and gear work atm. It's too much. For a new player...? No chance.
They need to do something, but as usual i only see stubburness coming from the devs in this regard. Gear and stats need to be simplified. Flavor should come from all the talent trees we got.
