So I was thinking about solo DGs and came up with a couple of ideas:

Lifesteal is either limited to certain weapons or super items (e.g gives 5% lifesteal for 10 seconds, 60 second cooldown).

Only X amount of shields may be taken from a ship, possibly with restrictions placed on splashing weapons; perhaps make player ships immune to such leeching altogether.

Things like capital ship travel fields restore the user's health over a period of 30 seconds (regeneration effect halted by healing/PvP).

Possibly OP

Very OP considering Sniper. But I do want. Will make doing Emp much easier :P

Charge up SA, jump on emp, activate super, and Surgical Vaardiger him to death.
