The faction PvP you have seen on Napa is the only PvP you see on Napa. Sadly, IMO, PvP revolves around LOAO doing something and everyone grouping up to fight us.
Once in a blue moon you might fight someone doing despise, rarely though. Kry does stick to themselves for the most part though they are not above calling in anyone and everyone to assist them when beaten badly. MiN and its various allies are so below skill its not shocking to see 500 of them hanging around in a house.
Alot of tamer fights happen so stat clears those types out, quickly.
There is a tram based guild who, when found spawning, will give you the best run for the money out of any other guild on the shard or I think anyways. They have good teamwork, skill and heart. Sadly I cannot think of thier name but, I believe, they deserve to be spoken about. A good number of times I have sadly underestimated them and got cleaned, not so with most of the other faction based PvP guilds.
This all said I think Napa PvP is fun and has it's moments but I am sure that other shards have better, or so it is said.
(lol the first posting by myself should have said everyone grouping up to fight CoM)
