Guild Wars 2

To save resources and have them load faster, have a circle appear on the ground that represents their team color. If you get 20 green circles around you, it means there is a team of 20 people about to aoe you into oblivion.

This should be easy to implement i think, yes?

or, if they should be visible to you, have a circle appear on the minimap with color depending on how many people are there.

Wait What? That would mean a certain servers would be very upset. They use player culling as a tactic in Wv3.
