I am horrible at pvp but I still got it using this technique. 1. Play rift 2. Don't equip the last word until you have your super, and you know you have easy kills. 4. Unequip your last word (so deaths don't count against you) and play the game, Focus on scoring the rift to boost your team to winning (most people are focused on kills so if you aggressively go after the rift your team will win 80% of the time) 5. Find a safe place and switch to you last word when you team has almost won. You get 3-4% with every win. 6. It's slow and steady, but it works. Took me about 15 matches using this strategy.
