First, I think that they are a good improvement overall, however they can be better:
I suggest having the "gravity" one that attracts asteroids also reduce collision damage similar to how the chomper's quantum surge works
When a targeted ship with the ability dies before the ability reaches the ship, the "projectile" simply stops and waits in space for a ship to come pick it up - I think it should either disappear or find another target (i.e. closest allied ship?) and be redirected
Map wraps - the projectiles need to follow the shortest map-wrap path, not direct path (so do cargo drones, but that's another story)
Science AI needs to start using these (at-least the heal one on injured ships..)
