Question about rules!

[Raekur]

Sorry for being unclear- the rules are not here for the sole purpose of being rules. They are here to help people, so the intent wins over the letter.

As for the rules being sloppy, take that up with Igiss.

I'll see if I can find where someone said you couldn't e-kill at cruise on your way in to attack someone and then fire while still flying past at ~350, but I know it's been said.

Soverign, there was a long discussion about the use of engine kill while at cruise.
The final verdict was you could not use cruise to decrease the flight time to the target.
If both the attacker and the target are moving at the same speed then there is no violation.
If the target is not moving over 200 then cruise torping is illegal.
Following this I would view the returning to formation tactic to gain a speed advantage would be illegal as it gives you an additional 70m/s boost to your weapon fire as well as being able to close distance when you should not be. Catching up to your teammate and waiting until your speed matches then engine killing would not be illegal, E-killing before matching speed would be.
This is very close to using cruise speed accelleration against a target that is moving at full thruster, thus yes, it would be a violation.
