SSS is a good start. If u dont know ur rotation enough to beat it i cant expect u to have good dps in raid when mechanics are implamented. Parsers are a great tool to see progression and sure as u get more use to the mechanics u will do better dps by putting your dots up anytime you wont be able to attack boss and knowing the good times to use your strong CDS and all the other ins and outs. Maintaining a conistent strong dps is important. But parsers are more then just reading your teams dps and dps progression. You can see your teams damage, what was hurting you, if a mechanic caused damage to others, your limit break, if you missed hits, and more. Thats why it should be in the game but only for the content it is needed for. People that dont want parsers are not going to do savage, so dont put it in duty finder content, kind of like how pvp has its damage totals at the end.
