it changes fundamentals in the game- namely the way people are organized or not organized. And yes the ones that will struggle are the ones already struggling
end game playes will get their event goodies an another 50% in tradable event items or tons of grout easy enough. The lower level players will already struggle to get essentials from event and then find themselves forced to be in very active guilds to have a shot in doing that in new style (presuming indeed what prom said that events wont be made easier by adding resources to guildquest- just spread the resources thinner on the ground elsewhere)
