A patch adds new content (the paladin class in patch 9s' case)
This is a HotFix... They repair bugged code but add nothing new to the game
The key point is you need to start a new game after each patch but can continue your saves after a hotfix
i know. maybe "moon raise towers" will reveal too much info of the game.
acturally, i think class can be added later, the game content release further is more important
patch 9 does many improvements, include boss fight strength, level 5 unlock, halsin's right manner, flaming fist consultant's clothes and so on.
