Imo it's worth it. I was kinda scared the first time I entered frontline and died like 7 times (only ilvl70ish). Nothing to be afraid of. As with any duty, just say yuo are a noob. Most people tolerate noobs as long as they are honest about it (and don't go under ilvl80).

As of now I find PvP more fun than PvE in this game. Doing dungeon farming quickly becomes boring. PvP, even though it's the same maps, is pretty different each time. Unbalanced, yes, however I've somehow learned to view that as a challange.
