Viper needs some major work

[Arkrayven]

the gameplay itself expecting or encouraging something that I am physically not capable of grates on me.

This is 100% a mental issue and can be solved by reframing your mental instead of asking for changes.

All content is clearable in all circumstances without hitting any postionals. Therefore, you can see that the game neither expects nor encourages you to hit positionals.

Rather, you are rewarded for the times and circumstances in which you can hit positionals, not punished when you can't.
