I don't think that the game is going to end as Dawntrail s supposed to be the start of a new storyline. That being said I am worried about the coding myself because of the nature of what they did to get a functional game up and running after the disaster that was 1.0. Honestly what they did was incredible, but it did leave them on a weaker foundation than you would want for a MMO. With this game being as profitable as it is I expect that the dev team has probably already addressed at least some of those issues as they really don't want another launch like the launch of Endwalker
