@qrikshank this is simply from a game play prospective and not really a PVP prospective. But just have fun, explore a lot, and try not to do very many quests. If the beta is anything like what the Alpha was, the quests will start to get extremely old fast and feel very grindy. I personally found that exploring was much more rewarding, as far as the overall experience goes. Sure, its not very rewarding for the loot aspect of it, but I hope that will change for the beta and we will be able to acquire/find rewards out in the world.
Friends do help make the experience more interesting, but you will certainly want to set yourself some personal goals to keep the experience fresh for you. Again, even playing with a group can start to feel a bit grindy after a while, especially if you are paired with 3 randoms that don't really communicate or share the same desire to play the game as you do.
