Did you all play at level 1? Or go higher to test more features? Guessing at least 3?

we did level 6 and it was very unhinged but fantastic, lol, we had a champion fighter, berserker barbarian, wild magic sorcerer, and circle of sea druid, really good mix of different stuff to look at

(I also ask, because in the new book, path of the world tree barbarian really intrigues me. Raging and giving allies temporary hit points every turn sounds so fun!)
