I think that the free [Honor] costume sets (grunil, taritas, etc.) are a fun thing to have in the game. I actually prefer a lot of the honor set appearances over actual pearl costumes. The only downside is that even having one piece of an honor set equipped removes the 10% death penalty resistance given by pearl outfits. I used to just suck it up and grind without full death penalty resistance. However, with the new expensive crystals / new end game spots that really isn't an option. I'd also rather not go through the trouble of switching to a grinding costume every time I want to make some money.

I can think of tons of solutions for this: 

- add a wardrobe feature, we've been asking for years.

- change the costume death penalty resistance to be active with 6 pieces equipped. This allows players to run one or two pieces without having the downside. 

- add pearl versions of these sets for all classes which count towards the set effect.

- remove crystals breaking :P

If anyone else has any input / solutions feel free to let me know 

Make them not RNG and unlocked progressively without having to pick which one you don't already have. It adds to the confusion of new players and locks them out from obtaining the complete set if they screw up.
