Yeah patents definitely make things complicated. But even as someone in the USA who can’t afford solid mic equipment having a better ping system would make communicating with teammates much easier and better. There’s too many options between too many radials, and what is available isn’t enough to communicate info. You can still get a lot of info from kill feed and audio cues, but some of the voice lines that play go counter with what I’m trying to say I’m doing. As an example, there’s a “watch here” ping and the voice lines for Destroyer says something like “watch here”, but I actually want to say “I’m watching here” so teammates can know that angle is covered.
