One of the best ways to get good (and have fun doing it) is to play with friends. See if your FC wants to come with, and definitely join some of the PvP discords. There's a ton of events going on between Rival Wings and Frontlines queue syncs that could give you some good experience and good vibes.
The two big ones to join would be:
discord.gg/pvprimal
discord.gg/pvprevival
Welcome to the party, man!
