We want the Olympiad to be similar to retail. The typical Olympiad class balance where a few characters are very strong against the rest, has been altered.
The BD / SwS and Phantom Summoner have been boosted. These changes also affect Olympiad game play. Furthermore, the increased DoT damage make any Dark Elf class stronger. The Shillien Templar in particular, has a lot more potency now.
We have not started the first Olympiad period yet. We wait for more nobles and we will take into account that Latin American players must be able to do Olympiad in a reasonable time frame as well.
