You lost me when you said I have to feed all my battle pets. Seriously no thank you. Any idea how long that would take?
A lot of this stuff I see being a bit more roleplay, but at the same time a game needs to simplify things to make sure you'e not just cluttering up everything. Flint and tinder is cool, but do you really want to carry a stack of both in your bags at all times? Especially when you've given up one bag slot because you needed somewhere to keep your arrows in that have become more expensive to make because of the new mining changes.
It seems like you just miss older iterations of the game rather than want immersion, nothing about the old talents was immersive, you needed to look up cookie cutters back then, now you can choose via personal preference in a lot of cases which is a bit more immersive for me at least.
