Well for gear, to LEVEL, i would say get as much Strenght and Wepon skill as you can, how to developp your character, well you have 3 paths to spend talent points into, every points you put into them will increase all the skills strenght used by that path, also you can put 1 point into the abilities that you unlock in the path.
Later ranks, the game feel pretty cool, im rank 36 atm, and im loving it, but its nothing compared to what Realm vs Realm will be in 1month or so when alot of lvl 40 will rise.
Here watch this if you want, Witch Elf PVP:
