plex warfare is very effective, on neutdragoons/talwars, it can be a somewhat annoying since fighting frigs usually means any dead ship will get insta podded. but if you plan accordingly you can have lots of fun for almost no expense. a respectable talwar fleet can go for around 20m, a perfect one for around 60m. and the difference between them is minimal.

if you want to pvp, stick to tanked dessies, frigs will die to easily. cruisers are only good when you have other pilots doing logistics for you. a fleet of mallers or Naugorors can decimate bigger fleets, and they don't require much micro.

and for lowsec ganking, with rubicon you can do it on Assault frigates, specially minnie ones, with warp rigs they are crazy fast. first get a suicide point bomber to hold your target then move in the frigs or just log them in for the kill. point bombers don't fit guns, only tank and point/web. (bombers have no targetting delay after decloaking).

with the new ghost sites, you will have targets. specially on the first months when the gold rush happens.
