What I'm finding is that the lower-ranked members of our clan help out a great deal. At the higher ranks, it's a pain in the neck to find friendly teams to score the Magus-only and effect-based challenges. The lower-ranked players don't have as much trouble finding opponents to score those and have ended up doing a lot of the work on them. Meanwhile, the high-ranked players are racking up Arena matches played (and scoring for Soul Protect if they're using Alchemist). It's nice to see that everyone can contribute meaningfully.
