I don't like it personally.
It's create too much visual noise with all the colours and it's not really necessary.
On top of that, it's another plugin/overhead that we can live without.
I respect your opinion presto, but I'm seeing too much complains about team flashing on dd2 server and insults aswell, with this we could avoid such things, and it's pretty much working on public since it got installed, besides I wouldn't suggest it if I really think it's not useful, thanks.
To be fair I've not really heard of anyone team flashing, it's quite a rare thing on DD2. It's just messy and although it looks pretty at first, it really is a big distraction and just not needed.
If you wanted this to catch team flashers, you'll be chasing it all day long on who accused who, when it was thrown, where it was thrown, was it an accident, bla bla bla. It's not the right tool to do this. If you want to catch team flashers, you sit in spec and watch them all. This won't really help all that much while your playing.
