Blademaster can be very hard to learn and everyone expects you to be pro from the minute you start pvping. You will most likely be called noob if you don't know how to stunlock or if you die a lot. However, if you learn the blademaster, it can be quite rewarding. Everyone needs cc monster in pvp and you will be very tough to kill.
Elf archer is somewhat easier to play. If you can deal Tons of Damage⢠and survive, you have fulfilled your role. EAs are fairly squishy, but you have quite a few escape mechanisms. From my experience with ea (on different servers though) as long as you play smart, you're not going to die very often.
