With how much time is needed to complete a Deep Dungeon run from 1-100/200, it feels unfair that disconnecting or a server issue can turn that time into wasted time. Considering how other content has been developed, even Savage content "end" fights, they seem to have their time more respected than a person attempting Deep Dungeon.
If I'm not mistaken a Final Savage fight has 2 phases, and those phases tend to be split but even if they weren't it's the difference between 2 10 minute fights or 1 20 minute fight.
A Deep Dungeon run however is a 30-60 minute time investment per floor depending on luck and other variables and if we look at HoH as 10 and PoTD as 20 and we assume a 1/2 ratio for 30/60, you are looking at 7.5hrs of time invested into HoH and 15hrs for PoTd.
Twice now with HoH I've reached floors 61+ and I've lost my estimated 3.5 hrs of time invested because of server lag leading to a d/c and server lag leading to getting hit by an AOE, so I've lost 7hrs of progress due to no fault of my own and yet no other content even comes close to that level of time commitment needed to clear and/or can be lost at the flip of a server being turn off.
With that in mind, I feel the most basic request, that if nothing can be done to "hold" your place due to a disconnect whether it be starting the floor again at the current time of your d/c, so let's say you are on floor 47 and you disconnect with 25 minutes left, you freeze in time and the game then "resets" you to the start of that floor with 25 minutes left.
Or, you remove the person from the dungeon, apply the KO and add it to the score modifier. Something like "Score/(1+(X*.25)" where X=KO. So say you get "KOed" either through a wipe or a disconnect and amass say 5 KO on Solo run. your score modifier would be divided by 2.25. So there would still be incentive to not KO if you wanted the High Score, but for those just trying to get a fair shot at a solo clear where they've lost countless runs due to server or internet issues, they would at least have a better shot at getting said clear.
And I'd even go as far as to say if you were to remove KO=1 from eliminating your Deep Dungeon run, maybe make it 10 instead. A server hiccup could potentially occur 1-3 times in an attempt, and 10 imo feels like a decent amount of attempts to give someone to clear a piece of content without punishing them for issues outside of their control.
It would just be nice if something could be done to in a sense respect peoples time more, so much other content added into the game does this yet Deep Dungeon remains the only piece of content where you could easily lose all your time invested after you already put so much time into it.
