@gskill150 I've seen this a few times and it usually means a group of people want to just PvP.
When it happens you'll often get people using the "No Escape!" text preset.
I used to hate it happening but there have been times where I've benefited when I was a solo player by digging up chests while they all PvP'ed.
If you think you're going to be in a teamed PvP battle and don't want to join in, it's just easier to leave than to push against the Ocean.
When you have all the looting commendations the only thing the Arena is good for is PvP so don't be surprised when that's all people want to do.
If you've already won 100 times or (160 for Pirate Legend), dug up 200 chests, completed 200 matches, finished in the top three 100 times and earned 1,000,000 Silver the only thing left to complete is the number of player kills.
It feels rough but there are two parts to the Arena mode that was set by the Devs as targets, people want to achieve those regardless of how they get there.
