Glad you had a fun experience.
PVP is synced to i150 so no harm in using the AF 2 stuff.
The main thing is choosing pieces with good substats.

I'm not great at PVP myself but one tip I can give is to make sure you have your PVP actions on your hotbar and understand how they work. As you rank up in PVP you get points you can use to enhance the actions such as reducing their cooldowns.
