Attributes can be interchangeable if needed such as for weapon talent requirements. Any extra bleed resistance or crit damage can be changed as well. This build is pretty survivable and pairs well with increased threat to protect your teammates and focus fire onto you. You could apply other attachments for greater threat if needed. This is focused all on health, self healing, slight support, and resistance. This build is better for a cover tank build actually, looking back on it. It is a recovering build. It is tanky but for difficult PVE missions it can just be a cover build. So cover damage resilience and abilities would work well with it. A crit healing smg can be used as well.
