I am not 100% sure about it, most of it probably for ship mastery i fly an Undine Nicor, but also CD reductions, then new starship traits and specializations. I would say its about 10-20% more damage then with lvl 50 and enough to overcome the regeneration barrier of the new and improved enemys.
My 2 cents on this matter. With high end mk xii gear and the right taktik Infected Space Advanced and Cure Space Advanced where already doable even with optionals on lvl 50. It just took longer than on Elite before. Now as i was leveling up to lvl 60 in my t5u ship, i noticed a steady easying of the difficulty of those…
