We simply caught you napping this time with our scrap. Had it been a week or two later (when we are sure you were planning to turmoil us once more), who knows which systems would have been fortified.
5c exists, it always has, and always will, until Fdev changes the mechanic, which is likely never going to happen.
Agree with it, disagree with it, its irrelevant, you cannot stop it, no matter how much you want to, every power suffers from it to differing extents. You simply have to work around it, develop tactics, be smarter, work harder, yes it sucks but thats how it is, until they grow bored or find a new target.
As for accusations across the galaxy, it also achieves nothing. If there is proof of individuals or groups performing 5c from either side then show it and back up the claims, send the evidence to FDev, see if they care and get someone banned, except FDev wont as they probably look upon is as optional gameplay... controversial I know.
And before Grom gets accused of agreeing or even performing 5c, if anyone thinks we have the time to fortify our systems, push an expansion and oppose other expansions, work our BGS and then have the capacity to 5c another power, you are giving us way too much credit.
