Fusion Genesis

Once you finish faction missions, main story missions and do the warzone and Legion raids you should be around level 50. If your not at level 50 yet then best place to grind these levels out is the first area of The Ark. Do the first two areas and exit, then repeat. At first you will level up very quickly, but the closer you get to level 100, the slower you will level up. Keep at it and you will get it. If your struggling to survive The Ark, purchase a better ship and better weapons. I used a tier 4 cruiser equipped with Battlegun 4s, a uncommon healer and a uncommon DPS sentient. Battlegun deals great damage, the healer to heal your cruiser (shields and hull) and DPS to help with shields. With this setup, you will breeze through. You can get better equipment than this, it's just what I used. Good luck!
