More transparency on the direction of PVP from SE would be helpful. So far most PVP changes have drastically been implemented, with no previous announcement, leaving players confused and unable to contest changes before they occur(Heavy/Light Medals, no 24-man FL, no 8-man premades, no idea of job changes, no knowledge of a start date for the next season of Feast, etc.). Leaving players in the dark instills hopelessness, an idea of SE's lack of caring about a portion of its community, and turns away new players when they ask questions and all we can do is say ""I don't know"".
Better communication on the direction of PVP from SE, dedicated PVP team or individual (mentioned in multiple feedback posts!)
