Someone on reddit analysed how many main cast lines are in the game. Wuk Lamat is 3rd

Wuk bashing besides, but you cant judge anything based on this right now, if you wanna see the true % you need to make a sheet and make a list for every single expansion to see how much of a expansion are spoken by xyz npc, because like earlier someone said that wuk has close to the same % then alpidumb has in HW

The post linked in reddit has that stuff included. It's something like Alphinaud has 20% of HW lines, Wuk Lamat has 24% of DT lines. Not a huge difference. Why there's a discrepancy in how their presence is felt, if not in nature then at least in severity, is open to interpretation. I would guess either some people are affected more by DT having many more lines in total than HW, or people like Alphinaud more so don't mind him taking up the room, but they don't like Wuk Lamat as much so are faster to anger. If that's the case... line count doesn't really matter, and this is just a new stick they can use to flog the horse.
