Idk, at times, when I get shut down, it's like wow, what the ****, why do I even play Snake. Then I remember he's really ******. And I go back to the drawing board, and remember my matches and see what I could have done differently, and usually, I find something, or I watched a video of someone else who got into a similar situation and got out. Snake is an amazing character, he's in our hands. People put a lot of effort into making us worse, and it sucks when you get *****, but suck it up and figure out what to change. I'm not going to say Ally does it, because he seems to do a whole bunch of ****. But the various other high level snakes do it, so can you.
But yeah, playing other characters, and taking breaks can be really helpful and nice too.
