I am certain Hoyt can script anything in Era xD That isn't the issue though.
I think the problem is that we have all played Era this long and have had no option to test out guns, so it is unfair to everyone who saved up and purchased a gun without the opportunity to test it first if it were added.
It will be easier for players to figure out which guns are OP and which guns aren't which will result in a lot of price changing or
Another issue is the possible glitch/hack abuse that could happen if this is added.
