Your team or clan only has 1 skinner, so you're coin hunting in 1 group always. You can't have 2-3 skinners per group and have em all split up, only 1 skinner registers at Skorr at the beginning, so your group will always coin snell-by-snell together. However a large strong group can bulldoze snells of foothills, KI, metz or wherever faster than a smaller weaker group, but there are lots of other places around the lands that have larger quantities of smaller coin beasts. In 1 hour, one of these smaller groups can clear NWF, Bears, SF, cloud, N plains, passes, maybe even valley multiple times and still maintain good enough coin flow to keep up with a foothills group, I'm sure of it.
Since these challenges are new, it's hard to tell who is gonna show up and how many per clan represented. Perhaps we just have to see who shows up and form teams accordingly, if it turns out to be too lopsided. However I don't think splitting up a clan that organized their strategy to let people form their own super group is the answer either. Although these events are just a small image of what the old Dun'ilsar's once were, they're still Dun'ilsars, which are traditionally clan competitions. I think the clans that organize together should stay together, no matter the numbers. Plus it's easier to score that way. The scoring was a bit screwed up on the V.I.A Dun'ilsar because 4 clans represented the winning team. If every event goes like that, there will always be X number of clans tied for first place, and there will never be a sole Dun'ilsar Champion.
It's difficult to think of new challenges that don't rely whatsoever on clan strength. Ideas for new challenges that give newbie clans as much of a chance to win as established high level clans would be good. I have an idea for a relay foot race across puddleby island, with different tasks at a few different checkpoints along the way (raising your fallen clanmate at checkpoint #1 for him to do the next leg to checkpoint #2 and <enter next task for next location>). Suggestions welcomed.
