How hard are raids and can I do fine in them without looking up a guide

[lucid hatch]

I'm new to the harder content in destiny and I want to raid but I don't know if I should join some groups if I have no idea what i'm doing

Theres the #find-a-sherpa

Sherpa is someone that will take a fireteam with people like you that don't know the raid and will explain it to you while you complete it :)
