Deliruim does not overwrite DK and never has, while I could bring up evidence of it I think it would be in vane. If you're interested in looking it up yourself do visit fflogs and check for parties with monk and drk in it and look at what happens when delirium is applied if DK is up.
Also you're not even properly discussing the shortcoming of monk but looking at turning it into a class for dummies. You have no facts to prove your reasons either but mostly because you feel like it or adjusting it to the lowest lowest common denominator where class balance doesn't even matter. What monk needs isn't removal of positionals nor addition of ranged attack, their personal DPS is nowhere near the issue, they just have no useful utility.
