Preferably learning how to run this Cobra. I should point out that my tactics for PvP vs PvE are completely different. PvP, I am 100% an evader. I don't even deploy weapons. PvE, however, and I'm trying to teach myself how to use my speed as a weapon.
The cobra is actually a decent railboat. If you can use your speed to maintain distance and take advantage of long range (5km plus) micro gimballing of the railguns, you'll be able to take anything out virtually risk free.
