Okay. I'm currently a Nihilist, and while I do enjoy certain aspects of it, I'm also a little bored. I've been thinking of changing guilds, either to Cacophony or Ninjakari. What I'm looking for is something that's strong in PvP, both one vs. one and in groups, in a primary role - not just aeoning and ecto + crucify to help someone else kill (yeah, yeah, oversimplification). I am bloodthirsty.

Anyway, any discussion of the current strengths and weaknesses of the two, based on my goals, would be much appreciated in helping me decide what to do.

Stay Nihilist and ecto/cruc more please.

I'd suggest bard actually. They're solid 1v1, and have great group potential.

This. Mag could use more Caco combatants. Also, don't go Ninjakari. Really, all they are good for now is Chaindrag,

I will prove you wrong as soon as I do all the other things I have to do
We can mangle hellishly

All of Mag's guilds are fairly solid right now, really.
