At some point I had the same realization about the six factions and the seasonal reset structure. Instead of trying to split my time randomly, I checked what structured options exist for faction reputation grinding. On
https://levelupper.com/marathon there is a dedicated Faction Reputation service that focuses specifically on grinding reputation for any of the six factions up to a desired rank. What stood out to me is that reputation milestones unlock upgrade tree perks, and since those reset every season, having a focused grind makes more sense. The page clearly explains how boosting works, including selecting the service, confirming details through order chat, and then getting the progress directly on your account. It also mentions that everything earned stays on your account once completed. For players who cannot commit hundreds of hours every season, that structure feels more manageable than juggling all six factions alone.
