Everyone stacks pure all resistance which will fall under elemental reduction anyway. Better than devoting a valuable stat slot for mere reduction of a single element. On top of general resistances, many people stack elite damage reduction, which works far better because it applies to all elite affixes.
I didn't make it too clear but I was intending 'elemental reduction' to be all elements. People stack all resist but it also comes at an opportunity cost in some slots, so an additional ehp stat on the less dps centric items could improve a characters stats as a whole.
For a slot like chest, I'd much prefer elemental reduction than ranged/melee.
Also I'll have to read the elite reduction, I did not know it applied to the persistent elemental effects (like how resolve for monks doesn't reduce them).
