Lets go with an argument of how monsters have insanely high MDEF or insanely high DEF, and we are forced to have penetration and tempest shadow sets. All because the same people shoving the sets down your throat, made monsters have those insane values so they could sell you the sets.
Congratulations, you've been played.
This just reinforces my thesis that they're not going to do anything else about it. Also, there are alternatives for every kind of player! Pick your now, and you'll receive a free shadow gear box!
1) Quit the game because this policy is stupid;
2) Quit the game if these sets are denied, because the current state of the game is ridiculous, and even the band-aid solutions are way better;
3) Play the game in crappy mode until you feel unmotivated enough, then quit;
4) Accept the solutions even though you don't find them perfect;
5) Accept the solutions even though you find them terrible;
6) Make drama on forum, threatening to quit if the solution that you really hate is ever implemented. Also, threaten to quit in the name of your family, your friends and your whole guild. But in the end, no matter what they do, your decision of quiting/not quiting won't really change.
And so on.
