Hello my name is AtypicalBarrettUser and i want to tell you that your idea for "Cyro Flashbang" Is a total Fiasko. I can tell you how to fix this so let's start.
Put every effort into your suggestions. Low quality suggestions are hard to understand and most of people don't know what you are talking about. Please remember that when you make suggestions you must think about thinks such as "Does this fit into the game?" "Is this balanced?" Or even "Is this even good?" The main things to balance your suggestion is to decrease it's stats. And also do not make Weapon suggestions. These are the hardest one to make since you must use your whole brain to make it balanced and to make it fit to the game. Thank you for reading this!
