Mercenary Tier problem

[AWT]

I can't seem to progress in the Mercenary system. Every day, I get an entirely new set of Mercenaries in all tiers. I read you have to defeat mercenaries of a higher level than you are, so yesterday I killed the tier 1 Mercenary. He was simply replaced with a lower level mercenary, and I still can't seem to make any progress (as tiers 1 and 2 are all "unknown", yet I'm already at level 48). I also can't find the arena. Any suggestions are appreciated. Thanks.

Killing a mercenary in a higher position than you just makes everyone below that mercenary (including you) go up one slot. So killing the tier 1 Merc just meant #2 replaced him, #3 became 2nd, etc. moving you up one slot.
You just have to explore around, kill mercenaries or do quests to find information on higher tier mercenaries that are unknown so they'll appear on the map and then hunt them down. (Some of the higher tier mercs are members of the cult as well, so that's another way to track a few down.) If you keep up large bounties, mercs around your tier can come after you as well.
The arena has a few different mercenaries in it, including a few of the high tier ones, and it's located on the north-easternmost point of the Pephka region, on the island of Krete in the very bottom right of the map.

Hey there,

I'm sorry that you've had an issue with the rank gained after killing mercs in Assassin's Creed: Odyssey.

This[www.ubisoft.com] guide might provide some useful information on how the rank system works.

Should you need additional support, please reach out to us again.

Thank you very much.

I solved the problem, by beating the "King of the Arena" or something like that (it was the objective in one of the missions). Now I'm permanently in the top rank.
But it was annoying that the game didn't seem to detect any progress, no matter how many mercenaries I killed, even higher ranked ones than me. The game just reorganised the line-up, and even replaced some the next time I started the game.
