Zahas, if we need to bring this to a rule lawyering state then i can tell you this much:
No rules were EVER broken. The sails ships in question were not even close to enter the gray areas of the rules. Everything that happened happened within RP, with a solid reason.
If you want to make a sair and blow the turrets of transports as you'd like. Please, DO SO.
You are in every way entitled to do so, BUT YOU MAY NOT KILL THE TRANSPORT.
This applies to everything, even a cap can "lolfire" your hull down to 1%, but aslong as there is 1% hull left and no blue msg, that ship didnt break 5.2 or any other rule i can think of, possibly 0.0, but he wasnt really unfair either.
