Cross-league trading is not allowed between long-term and three-month challenge leagues

After extensive player feedback and internal discussion, we are disallowing cross-league trading between the long-term (Standard/Hardcore) leagues and the challenge leagues (Archnemesis and Hardcore Archnemesis). You can still perform cross-league trades (at your own risk) between a league and its hardcore version (Standard to Hardcore, Hardcore to Standard, Archnemesis to Hardcore Archnemesis or Hardcore Archnemesis to Archnemesis).

We feel that allowing people to trade prior gametime into advantage in the new three-month leagues is an advantage akin to RMT.

This policy may change in the future, for example disallowing all cross-league trading entirely.

Edit: The same applies to race events. You can't trade items into a one-week race for example.
