Whats new in the expansion?

Cant find any reviews so i wonder whats new content added?

Read the page on the steam store


does the new classes bring new weapon types aswell ?
are there more QOL changes that not listed in the link u gave me ?

faster leveling
better drop rate
new gamble blacksmith
potion xp boost (expensive, late game drop)
craftable yellows 90+
new roguelike dungeon avaialble for free till the end of the year

Plus a whole heap of new loot with new item bonuses to skills, 2 new acts, illusionist (transmogs), hidden quests, new monsters, Etc.

So lots.

Faster lvling how?

Saw something about reset stats etc potion, but also XP potion ?
