My take on doc, I aim for using bandages and pills to heal and buff my team with emt and poultice. There's also more offensive slots and bomb Dmg to deal with any mutation dangerously close to you.
Weapon of choice is whatever you feel like, I tend to get a 357 and a Barret so I can deal with riddens easily with the revolver and stumble mutations with the sniper.
To be honest this build also works great with mom.
