I know this has been mentioned in every viper post here already, but trying out lineups with viper in custom games just feels so tedious, and this comes from someone who loves experimenting with lineups.

Just make it so that the poison orb doesn't have any cooldown, and that when you toss a new one, the old one dissapears instantly so you don't have to go pick it up. Do the same for the wall, so you don't have to end game phase every time you want to make a pixel difference in the wall setup, please.
