Beginner trying to PvP
“the scoreboard has me on the lower end of the team more often then not, as much kitten-80 points behind my next closest teammate.”
The scoreboard is irrelevant and is a bad indicator of your effectiveness.
In the beginning focus on one profession and build (change specs a few times in the beginning to get a feel but develop one primary spec), along with one style of play (bunker,roamer,decapper,1v1er, etc.) (and read up a little bit on your spec to learn its rotations and play style, some specs are harder than others)
Also focus on learning the maps and the win conditions for the map (watch out for the svanir, and guild lord noob traps)
Once your confortable enough in a 1v1, develop your map awareness and being able to know where the enemy is at.
Make sure you have fun, dont grind pvp!
Hope that helps.
