I always encourage productive, constructive feedback —
…but for this one, all I can say is this is an ill-conceived and mean change.
You gave players a heavily resource-constrained item that turned out to have a fun use against Titans, perhaps in a way you didn’t expect when creating it.
It’s impossible to produce enough of them to use them against Titans all the time, so this really isn’t a big deal.
Just leave them alone, and let people have their fun.
Who cares if they get some big hits on Titans, it’s not going to kill game balance if someone gets an extra RNG mat roll every now and then.
And if you’re concerned people are going to use them in PVE like Season 3 — again, so what? The number people can make are limited, if people want to use them there, so be it.
And if you’re doing this in anticipation of new game features where Titanium Shields would be overpowered, then find a way to fix that without killing something people enjoy.
This is a game.
It’s supposed to be fun.
Don’t ruin people’s fun for no reason.
And I say all of this having never made or used a single Titanium Shield.
I just want other people to be able to use them the way they enjoy.
