It's not necessary, and yes, it does affect others. Currently you have to think about ammo consumption and getting some new ammo at the right time - the drop rates are fair, and everytime you die and come back (full wipe OR res) you get your Kinetic and Energy back anyway. What you're asking for is the game to be further watered down and easier, and there are many of us who justifiably dont want that. I've beaten the raid, the prestige nightfall, and gone flawless, and not once has me or anyone in my group thought that the removal of synths were in any way a problem with our current system.
