My dedicated PvP char has everything leveled!
All weapon lines are at 50, all armor lines are at 50, all class lines are at 50.
Almost all morph choices are leveled as well (There are 2 or 3 i know i'll NEVER use so i omitted them for now)
That allows me to easily respec for any role i want/need ...
I have two characters that have pretty much everything leveled (other than Alliance War stuff)
My other characters not so much, I pretty much just worry about the main weapons they use.
However, all characters have all Class Skills leveled or will have them leveled. And, all characters have all 3 armor weights leveled or will have them leveled.
