Who wore it best?
Planetary Rendezvous is only worth it under certain circumstances. It won’t do you much good unless you have multiple characters of the same element on your team. It’s a Harmony Light Cone, meaning you can only take advantage of its ability with characters that follow the Harmony Path.
They typically support teams with attack, speed, and energy regeneration buffs. Therefore, they focus less on dealing damage compared to Destruction, Hunt, and Erudition characters, who you would ideally use to deal the majority of your damage.
If you have a team without overlapping elements, Planetary Rendezvous is basically useless because your Harmony character would be the only one who can take advantage of the buff. It might be less of a problem with stronger Harmony characters like Bronya, but still.
