I have played a bit more since making this video and noticed the generators and second bar on radars. Still haven't really noticed it on turrets though.
Thanks for sharing your first experience with T3. The first 5 matches are bots on the opposite team with human team mates. Since the patch yesterday this is now optional. The game is a lot more basic than previous Tribes games. I do play with EU players on the comp discord (linked from official discord) so maybe one day we will play together.
