Max stamina influencers physical types of damage including Poison and bleeds. Most of these skills cost stamina.

Unless your a hybrid a bow warden would want more stam and would put nothing into magicka.

As for health, only as much as you need to survive and that's a personal thing. As you get more comfortable with the game you should need less when doing dps and eventually not need to add any.

Edit: if your needing to put most of your attibutes into health and using bow exclusively is suggesting kitting the mobs your fighting. Arrow spray or the other morph are decent AoEs and walk backwards while using it. Just make sure not to walk into another group of mobs.

Get used to it and you'll be able to circle the group.

Also, blade cloak from the DW line will reduce AoE damage you receive or have a 2H for the heal skill it has. Just some ideas.
