Besides the obvious answer of "Yes I'd improve", using current savage content as an example, its much easier than prior savage.
But despite that, I intend to quit doing it, because its too much stress compared to the fun you have.
(part of the problem also lies in the fact I cant help my friends with it, w/o hindering their chest drops, so I need to stick to my raid groups times, and treat it more like work than fun.)
I did 1st coils in 2.0, savage in 3.0, and savage in 3.4.
And regardless of how difficult they get, they all have in common a lack of "fun" and too much stress.
I dont think ill do any more savage content come 3.5+
