Some simple and various ideas I’ve had:
See your helmet in first person (Toggle-able) (Very unobtrusive, very minor actually), but more importantly, see if your helmet has been removed or not.
This isn’t at all to obscure vision, only to show you if your helmet is still there.
Multiple assists count as kills. Maybe you’re not good at last hitting, but helping the team is helping the team. Something along the lines of 4-5 would be reasonable.
Put the team color’s on the gloves. Very minor detail, but as your team’s color is usually readily apparent (And if you’re forgetful like me), you can remember at a glance. Running and tabbing is a great way to get Steam to get you killed.
(Such as an emblem or stripe, nothing major)
Way to disable or greatly minimize chat. For aesthetics, or if you want a break from your team complaining about archers.
Staying near objectives should reward you with points. If you manage being a knight who just acts as a wall to defend the king, you should still have some points to show you’ve been doing work.
Removable crosshair, toggle-able. For aesthetics if you don’t need it.
Possibly an alternate death-cam option.(?) Losing your head on a hill can be kind of disorienting, even a little dizzying.
