Guild Wars 2

I’m trying to understand why there is a politics lvl 5 available to research for 20,000 influence but there doesn’t seem to be any things left to actually research afterwards.

The Guild Banquet and 20% Dungeon Influence research are both under level 4 and I don’t see any lvl 5 items listed.

I also quickly looked thru the wiki and didn’t notice any lvl 5 things that would be opened up by researching this.

Has anyone researched this yet and if so is there any new things that become available or do you think it’s a mistake or future update that may be coming soon?

Its assumed that there will be new things under the guild upgrades eventually. I believe guild halls have been confirmed as something that may be coming? Which might require politics.
