Abductor rounds are a very fun, low-violence game mode that I've recently found out is actually NOT in rotation.
This round type is admin-forced, much like Revolution or Nations. Unlike Revolution or Nations, Abductor rounds are not at all murder-y and can function without the aid of admins.
I've tried asking around to see if there was a specific reason for this, but didn't get a concrete answer.
If anything, my best guess as to why stems from this original thread from back in 2015, as it sounds like Abductor rounds used to be very buggy and couldn't be in rotation due to instability.
Since then, most, if not all, bugs relating to abductors seem to have been iron'd out, and the round type seems to be able to function without admin intervention, unless there is something behind the scenes only the admins see.
So to the general public: Would you like to see Abductor rounds become a regular round type?
To admins: What do you believe the reason is for Abductor rounds not being in rotation?
