As a relatively new member to the Yakuza, I have to say that I buck the whole "YAKUZA ARE GUD AT PVP AND ABUSED THERE SKILLS" thing that seems to float into these threads from time to time, being of pretty below-average skill in pvp terms.
That said, in the two weeks or so I've been a member, I've logged a good number of hours in my character and have been involved in pvp a grand total of two times, with the vast majority of my time being spent pirating, interacting with various allied factions around Kusari and - most importantly - posting cool, smoking and poolparty smileys in the Skype chat.
It's good to know that the majority of the people concerned with this thread understand that the faction is not some sort of uber-skilled gank fleet, hell-bent on 'red is dead'ing everthing in sight.
Dare I say the fight in Tau 23 today was fun, even if we had to beat a hasty retreat, not able to kill everything (our primary goal) in sight? Aye, I think I will say it was fun.
