Pretty simple suggestion really. Throughout the years of BD it can be a nightmare if you’re not avidly watching the map every tick to keep up with exactly who is who, because at the drop of a hat anyone can change their alliance tag and name
I don’t see why it isn’t more like the Name change system. It should cost a lot of energy/potentially blues, and have a long cooldown. Imo it would make the game a lot clearer to follow, and easier for those with less time to not get lost.
