From my perspective, seems there's some bias and maybe some butt-hurt from this post granted you collect these "clean" items.
Ill just leave this here:

Say what you want about that Sea Purse, but if it has to be explained why a q7/15 tactics inscriptable shield continues to prove invaluable to the PvP community, then I'll just simply shake my head at you.
We collect what we collect, I collect for function and sometimes rarity, but for me, Function>Rarity.
The lower tactics requirement makes it easier to achieve full armor of the shield and allows more flexibility for distribution and allowance for attribute spread in builds giving a small advantage in some cases. So let's break it down shall we?
Function? Definitely.

Advantage? +10AL to whatever you're coming up against = Awesome. 

Sea purse skin? Awesome to me, and not easy to find in those stats. 
A gold q8 uninscriptable Magmas +45hp/-2stance =
Rare = Yes, nice to look at in trade windows
Stats = Decent 
Advantage = Nope
. What real war wants to spec low strength?
I have no clue what the allure of "clean" items you collect. Maybe it's because you have to read less text when you hover over it?
You should be reading more, knowledge is power.
Function? Nope
Advantage? Nope. 
Rare? Maybe, but probably because most people rightly throw that crap in the trash.
