Just read this post on the official forums and thought it was so good i'd reproduce it here. I'm in the process of taking my main character on Eclipse towards a PvP template of some kind and I'm slowly starting to appreciate the depth of the SWG system and how badly it is misunderstood by a lot of people. If anyone here is seriously considering trying a lot of PvP I strongly recommend reading this post (original thread here btw) and a lot of the thread it is in. It is a very long post and will take a good few minutes to read and digest but I think it's worth it. This is the kind of explanation that is entirely missing from the SWG manual, website, anything official in fact. Complete failure to appreciate the concepts in this post is also what leads (imo) to the majority of the nerf calls on the official forums.
