We spent 23k in Consumables with 6 characters 11.2 games and lost all of it in the surprise round to questionable edge case tactics. Then proceeded to have all our spells and casters blanked and one dead by the end of the first round. only spells cast by our group after the game began were dimension door and plane shift and only just barely.
Other players had a different experience after they shared it we just had a GM who took everything to the extreme
Spoiler:
including us having to deal with a CR 20 creature with just less hit dice
