While I don't mind running the Competitive TFOs. It might be nice to lower them all to run one of them. Since, I got the Yeallow, 2 Diamond version of it, which is to complete 3 of them.
The only reason i say this, is even on normal, they can take a while to get them done. So far this is the only change I would suggest, since these aren't popular queues to begin with.
