Just a little patience. I've levelled 5 chars so far so I understand the pain to get to tier 3. Try to join populated servers so you can get a lot of assist xp. While you're not strong enough to successfully eliminate enemies on your own, help your team by healing or try to put your hands on a crossbow (that is effective even for low level chars). Patience will pay.
