Hey Bungie. You have an exploit. Go play Trials right meow. Javelin-4, In the middle dome there is the container the flag will spawn on.
If you're standing on the stairs adjacent, and look at the container, there is a space in the bottom right where Guardians can fall into, between that container and the pillar, and then use it as an invincibility barrier while capturing.
If you run up to it, which don't because its always a trap, people can jump out of that space and get free kills essentially. You can't fight back unless you're literally on top of them.
