Guild Wars 2

I died several times at WvW, which is normal and seems to be part of “fun”.
All I really needed is map finishing so I don’t want to spend money on repair.
I brought special WvW set of blue armor from loot and kept my normal gear in bag.

Surprise: after few deaths, some armor in bad (not equipped) was broken too.

I know it’s not a big deal, not a drama, no point to bother busy people with, but to me it just suix, so

I need to know it it bug or it made to prevent a smart use of gear?
If it bug, please fix; if not, please let us clearly know.

I’ve had this same problem in dungeons. Unequip armor for flame portion of CoF and it still gets damaged/broken while stored.
