Alliance size limits are set to be tested in Albion Online.
According to the blog post, the test comes after a poll suggested that 80% of players who voted want alliances removed entirely. To that end, the team is testing out a cap to alliances on February 26,
“From February 26th onwards, the maximum number of players who can be part of an alliance will be capped to 300. This is identical to the maximum number of players allowed in a single guild right now, hence it still allows smaller casual guilds to form an alliance just as before while achieving the goal of breaking up the current power blocks.”
Points sharing will also be disabled between guilds. The test is expected to last roughly two weeks, in which time the team will assess the data.
