My combat main is in the Caldari militia. For the past two months, there has been a continuous wardec between the largest corp and a few smaller corps due to blue ops with the Gallente. The large corp keeps to themselves, often attacking Gallente hi sec. The smaller corps are friendly with the general militia. I was there when the infamous incident occurred and the smaller corps definitely deserved the wardecs. However, the larger corp closely watches for any blue ops and there remains a bit of a civil war in State Pro to this day. And for the record, the war is very light on both sides, mostly just shooting opportunity targets as opposed to all-out war. Anyway, here's where the roleplay comes into it:
The larger corp has more of a l33t public image, but I believe they roleplay "Caldari Patriots" very well. In fact, the smaller corps often smear their leaders a "rp dorks" and give that as the reason for the wardec. However, the smaller corps opposed to them have rp public images, but seem to be all about kb stats as the reason to fight (at least compared to fighting Gallente scum).
Personally, I think they are both roleplaying without even knowing it. The Caldrai-Gallente conflict is a political one. Both blocs differ on what the relationship with the wartargets should be when there is a much bigger threat in the warzone. This is definitely a form of roleplay.
And as for the general roleplay in FW, it is hampered by the inability to form in-militia alliances as well as a reward for capturing territory. Maybe when DUST 514 comes out in 2026, things may change. Still, I am a little disappointed in the lack of Cal-Gal corps interested in system capturing.
