On this i can agree, especially in Savage, and especially by looking at stats in the parser itself, such as auto attacks, uptime, crit values etc
But the thing is, people want the parser for themselves so they can see their DPS and also expect other players to become better with it, and it's here that this isn't actually true, i already explained why, but going to add on it, people get better with both parser and guides, but then the try Savage and their DPS isn't enough even for first turn, and their gear is at least enough for 3rd turn (this is just a sample scenario i'm creating), so what went wrong?
They either didn't follow the guide, didn't test SSS or dummy rotation (SSS is still better than normal Dummy because after 3m mark some Jobs can repeat their burst and thus increase their DPS).
I'm strongly in favor that people should help bad players to help them become better being with or without parser.
