Champion patch v1.01. Brief summary. Sauna has been "balanced" as per suggestions below.
 * Sauna's Fury drain has been increased, as it was too lenient on this Fury reliant champion.
 * Stun on Assault Rush reduced to all-rank 1 second. Base damage is reduced, but scaling is better.
 * Concentration has been nerfed, as it now only removes slows and has a longer cooldown. His during God Fist max health ratio is now based on God Fist's rank, not Concentration's.
 * Vulcan Uppercut's knock up durations have been slightly reduced. Her on-target base damage has also been reduced. The AD ratios have been moved around while the Fury consumption now provides flat damage than % AD.
 * Fury requirement for God Fist reduced to 60 from 85. AR and MR reduced, while recast cooldown is now 10 seconds.
 * Eruption Core now inflicts a slow than a knock up and has a new activation requirement where it cannot be used immediately after activating God Fist.
 * Other nerfs (such as to range and damage) and a few buffs.
 * Added more trivia, lines and other items.
