Even if one likes the look of it, it's not a practical visual; it's where your character is located and can be blocked by others (you can see it being clipped/blocked by another player in that Strimtom video). How often am I standing knee deep in FvS healing wall with 5 or 11 other people all right next to me? All the time, usually with dozens of AoEs and other effects going off too, making it next impossible to see my character so I won't be able to see those markers. So I hope it's placeholder (or better yet that charges are removed from the system entirely).
