Sometimes I can tell when my current DM fudges a roll to miss an attack or reduce damage. He has a tell in the specific way he pauses and breathes before announcing the roll, then tries to hurry to the next turn, which only seems to happen when someone is in a life-or-death scenario, but “luckily” survives.
Should I let him know he has a tell? Will it be less fun (or more stressful) for him if he knows I know?
If you don’t mind dying, tell them and tell them they needn’t save you. I would tell tree and ask them not to do that, at least with me. I’d prefer if they wholly didn’t but meh
These days I play more 13A and it explicitly discourages such behavior too
