All in denial over the community's real favorite faction
Anyone out there wanna play as a nitty gritty Privateer maurader/blockade runner? How could you not? Stop denying yourselves lif'e's simply pleasures. Join the LRF!
This is mostly just faction members promoting their own faction, so the largest or most devoted is bound to come out at the top. Being large or devoted doesn't necessarily make a faction good, though. There can be large factions that are devoted to ruining everybody else's day.
Unfortunately for Lucas, Lucas isn't a large faction, so even if its members played dirty here and promoted it themselves, the faction would still not be among the top three. But the members of Lucas are above that. I'm not a member of Lucas, but I know the faction, and I can vouch that they are the one who I have had the best interactions with since my join date of March 2011.
Although I believe that there is no such thing as a universal "best" faction to satisfy every character's RP/PVP needs; maybe the best faction is the one to which you can happily come back no matter what happens to the said faction.
