Help?

Cannot play Halo 5 due to the latent servers I keep getting matched in.

Is there a solution to this? Have no issues on any other game including Titanfall that also uses dedicated servers.

Live in the U.K, followed all troubleshooting steps, fantastic ISP better than average upload and download speeds, open NAT, no packet rate loss, low latency.

Please help I want to play Halo 5. Thank you
