Chestplates are decorational and provide protection but on Divisional and Divisionless personnel just looks outrageous. Seeing AEGIS with titanium ruins immersion and logical lore sense.
A corporation like AEGIS "realistically" would equip their personnel with standardized gear just like any other military. As any other military you wouldn't be able to buy or carry your own gear.
Solutions?
• Do not show chestplates on AEGIS
If you don't want to remove chestplates?
• Make Heavy and Titanium models for AEGIS look more "lore friendly". Black and fitting our models.
• "Disable Cosmetics" button in the settings
Plus looking all alike would just improve the game immersion from personal opinion.
