Right now we almost have no point to speedrun Expedition content. Since the rating is among several servers it is hard to compete. Also rewards don't include any packs like temporal vortex rating does (or other juicy rewards). So a lot of players are not interested in it at all. I.e. with packs as rewards at least some alliances could brainstorm this thing and the whaliest nember achieve top rating.
IMO this piece of content is important since we are not doing much at the otherworld at the moment. We only have ancestral ruins to do and rewards for speedrunning them actually way better and obtainable. But this content is not the greatest for streaming or finding strategies. It is time consuming and random. The ranking for it is also personal and server local.
Probably you should change the reward system for Expedition Speedrun to involve more players
