Very accurate! I hold the Crucible record for fastest clear time, 11 seconds before my DW physical Opressor dies 
I have so many failed builds but people can’t see the unsuccessful attempts, right! And I play without searching for information when I started. My first character - Witch Hunter died 32 times… on normal difficulty, including twice in a row against Venomstinger.
So game like everything in life have learning curve. For some learning is easier than others. But if you do it with passion, you can become better!
