I want to end ranked leaderboard prizes until such time as the leaderboard and general ranking system can be overhauled. These prizes are consistently won by the same accounts, which often abuse the system in any way they can.
A few of the known exploits include but are not limited to:
Win trading
Carefully timed cueing
Purposeful ties for first place
Rank point scalping

While skill(or a battle helper) is necessary to achieve a leaderboard position, it's just as much about knowing the ins and outs of how to find favorable matches and avoid bad ones. Until the system can be redesigned to make a fair and balanced ranked system, there's no reason to keep padding these account owners' pockets with $15,000 every month.
