The MOD has the feature to deploy the whole suit from the backpack so everyone can assume that the suits are transformable so it would be a convinience as well as a cool feature and for sec an identifier to have just the Helmet not be "removable" but for it to retract in a similar way as the Explorer suit hood.
It would also be a convenience in the way that you don't need to remove the whole suits just to show your face when needed which is a slow process.
In my opinion from the cost perspective of Plastitanium it should be more durable than regular Plasma glass or have other benefits because I don't see an benefit of making it other than asthetics but even that sacrifices the durablility.
So my suggestion is to either nerf Plasmaglass or buff Plastitanium glass in some way.
