Just Flip lone wolf and Improved steady shot and it wouldnt feel so bad to not take it.
I still personally think Marks shouldnt have a pet as it is against what they are offering. But if you offered people the ability to skip around Lone wolf instead of making it a mandatory talent it would be less painful and you could just have your pet with 0 issues outside of swapping them.
Sure Fort of the bear should be baseline and not attached to a pet.
