I can see where “leeching” could be a problem with FA. However, the local solo leaderboard for each assault is pretty transparent and you can see who contributed the most in the rankings. Those individuals will be awarded for their contribution with extra currencies to shop for things they need (gear, active skill trainers, and museum pieces for characters). Thus, those individuals will be able to move forward faster with upgrading and maxing out their character’s skills.
Furthermore, there is also a Ticket contribution local leaderboard where you will see the contribution of all 30 members (assuming you have 30 people in your faction) and their daily contributions through activities. This could be a bad thing or a good thing, as you can see who is contributing to the faction pool and who is not… This gives you an opportunity to help them out, offer advice, or help their gameplay. It is a faction-focused event where you will be most successful as a whole unit and not just a few carrying the whole faction. If any scenarios of “carrying” or “leeching” show up however, feel free to post about them so that we can figure it out together.
