I need advice from higher elos. Should I not main cypher in iron?

So I recently just got out of iron 3 and back into it following some of the newest players I've seen. And I'm questioning to myself, should I stop playing cypher, sova, and fade and start raining entry heroes since most of the time I can't depend on my team when entering. And yes, I entry the site with a cypher or sova but in a systematic way. I only ever die when they got me by a blind spot, or I panicked cause I'm getting attacked in multiples angles. This is my first fps so I really don't know what to do
