Once you get it to the 10th ‘level’ and you get to pick another SP, does the +XP gain stop working? I understand it’s an add-on in the loadout section so you should always have it, but does it keep going? Even if you’ve moved on and you’re using RG or PF? I just want to be sure before picking anyhting…
You put Fast Track in your loadouts and it works as long as you can get xp. They are smart too so dont start a match with it in loadout then swap because you’ll only get the xp based on the performance when you had it in your loadout.
