Do either of these features cause lag or bugs with them being released in an incomplete state? If no can we just wait a week instead of having to do another 1.5h maint? Think of all the boss resets this will cause please.
In short, yes. We should not let them stay enabled on the server, as they are using outdated code, are calling for code that's only available in the full release of 2.5, and may be unstable. While we'd love to let them stay on for the week, it may be poor to do so and could cause issues.
