Ok, so I have this cute pet that I picked. It attacks things and I can use fish to make it uber. The problem I have is that I don't seem to care very much about him, except that his trips to town are very convenient. What I want to know, in hopes that I will find new appreciation for my pet, is how important he really is to my survival and progress.
Here's the question: Assuming I give him the best collar and tags I can find, how much of a difference can fish really make?
I have searched for questions regarding the effects of various fish and therefore understand their various effects, but they don't seem significant. As a result, I seldom bother to feed fish to my pet. I've even assigned a hotkey to fish feeding, but still seldom bother. The problem is probably that I do not know what percentage of my DPS is generated by my pet, and therefore do not account for him whatsoever. (He is useful but unaccountable.)
