Back in university my Hmong friend wrote a pronunciation guide for non-Hmong speakers that went, "If it's spelled in Hmong, you're pronouncing it wrong."
This would allow you wear one pair of sunglasses normally, and another pair on top of your head. You could then make a second costume where the only difference is that you switched the glasses around. I fully support your idea.
This is even more annoying during various events. Accepting a 'defeat 50 Carnies in Peregrine Island' only to see a 'Zombie attack in Peregrine Island' alert is infuriating. It's also the reason I run most arcs via Ouroboros, I can drop them if a mission turns out to be particularly stupid.
I like the idea, but I'm not crazy about the million inf part. If it's going to be gated behind something, it should be winter event related, like candy canes or a badge unlock.
I don't mind Crey tanks having high lethal resist, the problem is that from level 46 onward, every spawn seems to be all Crey tanks. This means that my claws/spines/dualblades/katana/broadsword/battle axe/savage melee characters skip 46+ Crey missions whenever possible and I'm not sure that's what the devs intended.
I've said this before, but what I hate about the Freakshow rez is that when I do 5 Freakshow missions and 1 Council, I'll waste 20 seconds after every group of Council waiting to see if they rez.
