Guild Wars 2

Here is how.

SoloQ on Ranked arena. Have more than 50 rounds. If you run good build with fine rotation, you will get around 65% of winning rate.

This proves your build is good and also, your personal skill, like rotation, is also good.

(more than 70% winning rate it is god mode)

When I search for builds I do much tests on the golems first.
Then I try to kill Svanir and Chieftrain quick.
After that I start practice in yolo mode.
Builds I have created enter ranked when I had high scores often in unranked.
Along the way I always tweak and change things.
This makes it a good pvp build for ME, but its like SSoH already told you …
This has nothing to do with win and lost rate.
What about all the rage quitter and disco ppl, for example.
