I have fixed the issues with dynamishelper and it is now showing the correct staggers for "hopefully" all dynamis mobs (i think i might have missed some goblins i need to double check that).
The addOn needs a rewrite from the ground up, tables can be optimizes and the zone handling is not ideal but in the meantime this will actually make it work again so people can use it.
Since i can not upload the lua here, I will submit this to github and take on the responsibility to maintain it for the future.
