Please stop being so entitled. You don't have to have everything the game has to offer just because you pay a subscription each month ><
If the mirror is so hard to get, then yes go and get yourself a weathered weapon or progress your relic and move on with the game.
If they raise drop rates on rare stuff, then everything will be easy to get and everyone will have it. Then what is the challenge any more? It's no longer fun, you don't experience the exhilaration of winning something so rare when it does drop and you do roll highest. You will have everything and there's nothing left to play for.

For what it's worth, I lost roll on 4 Nightmares before I won a Gufflaxi with a 99. I didn't kick and scream over drop rates, seeing they drop at all was motivation to keep trying and it paid off.
