Shattered Kingdoms

Unless there is an incentive to PvP in that area, it still leaves the question of how people can kill other people now.

It's incentivized swashbucklers, but unfortunately taunt is still very risky to use in PvP (It's still a 2 round lag) and breaks pretty often, especially if the person you're targeting isn't front rank and/or has access to etherealform. Swashbucklers are also objectively awful to have along in PvE compared to any other similar class.

SK's always been a game where it's all but impossible to kill someone who's intent on avoiding even PK, meaning that most kills need to be gangbangs or ambushes: Unfortunately it's not gotten much better in that regard. For that reason I haven't rolled a character with the purpose of excelling in PvP since Surrit, who I retired 2 years ago. It's simply not worth the effort anymore in my opinion, as other games provide the same enjoyment of competing with other people on a level playing field without the mandatory 1-2 weeks of downtime in between losses.
