I like how they put "hidden" shit through the game, dont care if toys or flavor trash, it's pretty funny because it is like playing war3 and finding hidden items or hydralisk in the forest.
Also drak'thul is a big cit from tft maiev campaign.
Btw if i recall correctly there is in every class hall a map of broken isle with "X" on each region, basically any raid from EN to ToS BUT there is a X on highmountain that i dont get what could be.
