Too much is tied to the character model. It would be best to separate it all even if it means dramatic changes.

I would KILL for a technical update that introduces 0 new content and simply makes gameplay smoother. Everyone can name at least 3 seemingly small things related to UI that if changed would lower the frustration level of the game dramatically. For me it's;

1. blinking. because too many other things are needlessly tied to it.
2. menus that offer you a selection from a list. atmas, assaults, campaign ops, reward lists etc. 3 options visible when there are 10 pages with 10 options each and the game has to redraw the menu every time you go back or forth a page drives me insane.
3. any doorway that hijacks your controls to show a cutscene of your character walking through it.
