They could copy the voting booth from Runescape 1-to-1 (including the lack of polygons!) And it would be a net positive

They could use it to ask abot how players feel about changes, or about what players want in the future

Give it an archievement called "I Voted!" And a buff for the day when a vote is held (free teleports, longer food, exp buff), and that should be enough incentive to get players to participate

Of course, options such as "I dont care" or "I dont play this job enough" should be avaliable to avoid people from voting random things to get the buff, but eh, it would still be better than nothing
