My wolves don't seem to be getting talent points for leveling up anymore, unless they only give them out at certain intervals, or there are diminishing returns. My companions do still give out talent points for each level. Are wolves bugged or is there a diminishing returns percentage thresh hold?

I could be way off base, but my understanding of how the talent points work is you get one whenever the guild levels up. And the guild level is based on your overall companion and wolf levels (or based on how much exp. they get anyways, cause most of my companions are already level 10 but the exp. they get from playing still seems to count). I don't know if it's an exact 1 to 1 (like, your wolf gains 100 exp., so your guild gains 100 exp.) or not, though.

(Edit - did a little bit of experimentation by having the campaign and my guild open in separate tabs and flipping back and forth. I can confirm the exp. is 1 to 1.)

It seems guild levels follow a similar xp structure to profession leveling. So they get increasingly harder as you advance (fun fact for the professions at least, once you hit level 90 you’re halfway to complete!!). Here is the guide to profession experience, our guild has advanced too quickly for me to follow along and confirm if professions align exactly but I’ll definitely be keeping an eye out when we can create/join additional guilds and I have one that moves a little slower!
