people do not have too much incentive to place bounties on each other currently... this isnt an overly active forum and many members would place the minimum, just to be a bounty killer.
At the start, its all good. Fast foward 3 months, and there lots of bounty hunters, and few bounty left.
How about, we make it kinda like ladder.
You 'buy' a license to be a bounty hunter for 10 gp. You can then hunt bounties for the next 14 days.
The bounty?
The bounty hunter's license fees of last week, distributed in a decreasing manner of the top 10(or top something) players of last week's ladder, minus 5% for TFW
Example:
Today, Jed and Keyser and a bunch of people bought licences. Each lost 10gold, making the pot 95gold(assume 10 bounty hunters total)
Fast foward to when ladder ends in... 2 days....
top players of THIS WEEK is
ladderbot6454
ladderfarmer34
noobilly5346
etc etc.
So, ladderbot6454 has a bounty of 44 gold on his head, ladderfarmer34 has 40 gold on his head, noobilly5346 has 35 gold on his head, etc etc.
The bounty is accumulative!!!
Note, if people are using alts, this COULD be abused. But then again, the original system above would suffer a similar fate.
Also, it would help decrease the top player's ranking if they lose.
