I absolutely hope they would homebrew it in by default where let's after your 3rd attack or spell miss, you start getting increasing attack/DC modifier until you finally connect something.
They do need to make sure you can't reasonably game it by throwing some spells/attacks with deliberately lowered DC (scrolls and such) to prop up that big one. I imagine this probably won't be a big issue, because trying to do this would be unreliable plan AF, but who knows.
And absolutely that example of 8 misses, really that should not happen like ever, IMO, even at cost of them making that 8th attack/spell assured hit unless target is outright immune. At this point you need to be some absolutely hardcore D&D fanatic to enjoy something like 8 misses in the row.
I never missed 8 times, but when I couldn't hit Flind with 3hp for 4 times in a row that I started to get irritated.
