Well after having a lovely conversation with AGS | Refleax, he recommended that I make this thread to start a discussion around this topic and to see the popular opinion.
Currently, with NW, your in-game names/tags are not directly tied to your Steam name, meaning as an example; with NW, my in-game name could be 'Svea-Livgarde_Kpt_Carolus' while my steam name is simply 'Xaime'. With Holdfast at the moment, your in-game name is directly tied to your steam name, so as an obvious example; my steam name is 'Xaime' so my in-game name is 'Xaime'.
While yes this is simple, I personally don't like the idea of having your name tied to your steam name. The in-game names/tags you had for Warband regiments, in my opinion, made it "unique" and overall easier to organize and identify regiments/units when in-game. It also made it easy to know what rank members are, etc.
Of course, you could just easily change your steam name to accommodate this but again for me personally, I don't want to make my steam name 'Svea-Livgarde_Kpt_Carolus' just to keep and show the "uniqueness" of the tags.
Maybe I'm the only one with this opinion. I'm interested to see what your opinions are as I'm sure the developers are just as interested.
