Party up, run Elite/R1. 6 pulls on Elite > 3 rerolls solo.
You've had this discussion at least a few times by now (3 minutes searching finds
this thread from three weeks ago,
this one from two years back and
this one from 2015), you know how this works.
Farming gear in DDO isn't terrible by any stretch of the word. 6 players on Elite pull an average of 2 named items/run. Quests typically have 4-5 named items, and appear to have uniform results. If you ransack with 6 players on Elite, you'll average 16 named items. With a 5-named-drop quest, your odds of pulling a specific one are 96.2%. With a 4-named-drop quest, your odds are 98.4%.
Nothing is guaranteed, but you can hugely improve your odds pretty easily - up the difficulty, get more people pulling chests.

If the first time I ran any quest/raid I got offered every named item in it, what's the point? Seriously, why bother? Skill, difficulty, whatever - who cares? 20 raid completions as you struggle through on Normal to buy a raid weapon? Nah, just find a PUG and do it once. You don't even need to bother to learn the mechanics. Where's the magic? Where's the accomplishment?

I'd be alright with adding some chain rewards back in, help steady the loot out a little. But party drop rates are nuts in DDO, and being able to pass named items makes this game so much friendlier than so many other games out there.
