Posting this here so hopefully Arenanet catches this and fixes this:
Elemental Attunement: Fixed a bug in which the regeneration boon was applied to allies when an elementalist attuned to water for a second time.
This is incorrect, no bonus now is applied twice, including swiftness which is a large nerf to swiftness, quality of life, mobility, flexibility, and the uniqueness of weaver in general.
Please either make it clear in additional patch notes that swiftness no longer stacks also or remove the unnecessary/faulty change from swiftness.
Many classes outrun us even without this change.
Assuming it is a bug, can this be fixed? People deserve to know/no stealth nerfs or for it to be fixed. Thanks!
