It's more after days of reading the DD forums, and hearing your statement echoed by others who are like "I don't know what the BFD is."
so if someone says the tutorial is hard due to RNG I personally imagine that they'd had to of been screwed REALLY hard for that to be the case.
Try dieing in the 2nd turn on the second fight of the tutorial. Try that whip attack critting for 15 damage on both your characters. Try following that up with Blanket Shot critting for another 8 to 10. Try starting the game with your two best party members at 85/100 Stress, or already afflicted.
It's not hard. It's just stupidly random, which has classically produced the result of some players saying the game is too easy, and some saying it's too random. The difference I see is, people who have experienced the randomness at its worst understand the game can also be easy because of it. The people who HAVEN'T experienced the randomness at its worse are acting like everyone else is just whining/needs to L2P/confused...and/or bragging and complaining that the game is easy. Or acting like the source of people's pain is a mystery.
and it's kind of like Blood Bowl in that managing the risk (and knowing when to submit yourself to RNGesus) is part of being good at the game.
Bloodbowl is not a valid comparison here, and here is why: in Bloodbowl you know what's coming. You can see several moves ahead, you know what your enemy is capable of, you know what your own guys are capable of.
That is not DD. You have no idea of turn order, the content of encounters, the make up of an individual dungeon run or the range your enemies and characters are capable of achieving. I've seen the Bounty Hunter crit so hard before he could have nearly dropped a boss with that one attack. I've had some characters resist death like 7 times in a row. I've had enemies one shot my own guys (to Death's Door) from full health with a crit. There's very little you can plan for in DD other than having 4 characters and healers.
Bloodbowl is an entire other order of strategy above DD. They're both random games. One gives you plenty of information and preparation and then fucks you with the RNG. DD just throws you into the unknown and then fucks you with the RNG.
