Thatâs false, you can do more dps than your sims as they are an average of a lot of attempts, you could get super lucky with procs and deal a lot more dps than what you sim.
Also sims usually follow hectic cleave or patchwork style fights so they arenât the most accurate.
@OP, The best way to master your class is to do a couple of steps.
First read a simple guide, any guide with a little bit of merit to it for example icy-veins guides, get a general idea of what your class is and better understanding from it
Afterwards turn on detailed ability tooltips, read every ability and passive and understand them and how they interact with each other.
Then find a very good player, talk to them if they are willing and ask them for instructions, or you could watch a detailed youtube video from a very good player out there if you could find one.
After seeing through the eyes of a very good player, try to imitate their game play but with an understanding of whatâs and whyâs ( gained from asking said player / watching them explain it on the video )
After that start applying your own style to the gameplay, shift it to suit your needs and the situation and apply your logic to it.
Now practice a metric ton.
Viola you should be pulling purple logs now.
For orange logs you need to understand your class perfectly by knowing every little interaction there is to it, getting ultra lucky with procs and playing it perfectly with the best conditions.
Also donât use ability predictive addons like deja said.
There are however addons that help you track stuff which would improve your dps a lot.
Also being comfortable in a fight can really help your dps, a lot of dps get nervous and focus on not failing which in turn makes them lose dps, so fight knowledge will increase your dps by a huge sum.
