How to Get Better at Understanding PvP
Well, you mentioned playing other classes, which is the best option in my opinion. But other than that, you can also check streams with experienced players and see how they play and what is important to dodge/counter.
You can check metabattle for most of the builds that are used, or you can just go to a build editor and go through every trait and skill of the profession you wish to learn, although you won’t learn the animations of skills this way, it will give you an idea how the skills play out so you can start recognizing them in game when you see them.
As you get experience the game will slow down and you will be able to see what is going on most of the time, it comes with practice.
since i only like playing engi, ive more or less cut myself off from learning by playing other classes. in that case, the best method ive found to learn how to fight someone is to find a person who knows what theyre doing and duel them. repeatedly. like 10 times. get your face smashed in until you do your stuff differently enough that you find something that works.
