OK, viper molly should not do full damage it should be to remove a person from their position. so reduce the viper molly length and max damage 30-50
Mortadelo [#3]I think the perfect nerf and fix for post plant meta would be make the molly work like the smoke, just letting you live with 1 hp, (but without recovering the hp back obviously). That will force Viper to pick, but will still have all the advantage
(The idea it's not mine)
