I have been reading this Merry Mayhem thread and thinking about it, but I still can't get my head around some issue.
Like, what is the motivation of Planet Calypso behind this event? I've always thought it is to generate income : get lots and lots of players to hunt, hunt and hunt some more using the strongest weapons and thus spending a lot of money. But I get the impression many won't participate because it's a team event and they won't stand a change solo.
Is Merry Mayhem a team event or not? The prizes are geared towards solo players, however, they way this event is organized, teams clearly has an advantage. So, I've been thinking : how can this be an event where the fastest and best solo hunter wins? My answer : tracking by loot.
The four mobs of Merry Mayhem carry a worthless, stackable, item. This is called a Merry Mayhem Coin. The TT is 0.00001 (that's the least it can be?), it can't be traded and can't be dropped. (Like that urn you get in one of the missions, can't do shit with it). This Coin is dropped very common, but only in small amounts. Kill ten and you stand a very good change to loot seven stacks. Higher maturities drop larger stacks. Going from only 1 to 10 - 15 that is regularly dropped by Stalkers.
At the end of Merry Mayhem, give your big stack of Merry Mayhem Coins to the quest giver and Planet Calypso can register how many Merry Mayhem Coins you've looted and thus how many points you have.
Now, to prevent teams with "looter takes all" to take the lead : set the mobs to "shared loot" and disallow teams for participants. Or better : only allow certain teamsettings that makes it impossible for one hunter to loot all the Merry Mayhem Coins.
