I'm new to this sub-reddit but I generally get the idea that you will not find a satisfactory answer to your question. You're basically asking a competitive group how to go about your casual build. MH is great in that, if you can play the game skillfully, you can do whatever you want to some degree of success. You might find information better suited to your question in the main MHW reddit or some bow specific one if it exists.

My two cents is that you definitely don't need to get max damage before doing support stuff in order to not be a burden, but wide range on bow probably isn't it and some of those stamina skills need to go. Perhaps consider a status based build where you prioritize para/sleep instead of healing/buffing allies.
