I forgot about daring adventurer completely, even though it's my favorite to max early. That double reward when clearing the quest tiers is too tasty.
I don't know what you are responding to here otherwise. That INT shouldn't have synergies with other trees? That INT shouldn't have a capstone of some sort that gives you some cool thing as a reward for your deep investment?
I thought you were continuing Old Crow's argument so I was responding to his and your post combined. If you don't think INT is inadequate, why do you think it needs to be bolstered. Isn't that double reward of Daring a cool thing?
