i'm pretty sure i saw a thread about this but can't seem to find it so i'm making another just to get quick answers.
I did an edit of the 30k mask and you guys can post your opinions on it. Still working on it and you have an option with or without the gas tank.
I also wanted to make sure it still relatively resembles the old mask- you probably won't be getting an updated mask that looks completely different to the current.
(also the black visor is transparent, i'll post a picture of it on my character)
edit
another option is a gold and black version as the gold was removed from the 50k and replaced with diamond.
