Well, think about it this way, getting the right drops is like getting a Ridill or E. Body, not common but it will happen. I mean, how many Fafnir's do you kill that just have N. Legs when you don't need them? The way you go about getting the gear is different, but the appearance rate of the gear (completing an item) is probably on par with Kings.
Wouldn't it be nice if more things to get good items required more skill/effort and less luck/time?
Example of how good items should be: shadow mantle, and Kirin's osode (back when it was a big deal to kill kirin)
Bad example: Any land-king drop
P.S. Yes, I know some ls have dynamis lord on "farm status". There's still some measure of luck involved which still makes it fun and challenging. Getting gear shouldn't be like 80-90% luck, is what I mean.
A handful of things that require mostly luck is ok, this is just a "change of pace" kind of thing. However, that luck coming from having to outclaim 5 other linkshells is poor design.
