Hey. I have been playing Viper since launch and have always looked forward to any improvements to this hero. Despite all the complaints about this agent, I always liked her, but I offered several buffs for her that we can discuss.

1. Her Toxic Sreen ability can help the enemy figure out where Viper is if she throws her and the opponent sees it. My suggestion is that the enemy cannot see where the wall is until the Viper activates it. This can be done like this: Viper launches Toxic Screen and the capsules of this wall will hide underground and crawl out from under it when Viper activates the wall.
2. Toxic Sreen and Poison Cloud after the death of Viper should remain in effect for the same time as Viper's Poison remained before death. For example, these abilities were activated, Viper could work for 12 seconds, but she died, they should be active this time. After all, Omen and Brimstone smokes work if they die.
3. Omen and Brimstone can pinpoint where their smoke will go. Viper does not have this ability and the player cannot know exactly where the smoke will fall if he did not know it before, so I suggest that Viper can see on the minimap where her smoke will fall. This will help ranked players to use this ability more often and more beneficially.
4. Another good buff - Viper was able to adjust the Toxic Sreen length. This will help in cases where the player does not want to use the full length of the wall.

A couple more buffs that a lot of players support. They are already more powerful than the rest.

5. The Viper can take the Toxic Sreen and use it elsewhere.

6. The enemy slows down slightly in the Viper smoke.

I hope you enjoy these buffs! You can also suggest your ideas in the comments
