I do not recommend new starters to play the game solo. The game was designed for party interaction, and by starting off soloing immediately, you will miss out a lot of the game's interaction.
I played with a party for many, many rounds, before I finally decided to solo. I took the next step because by then, I had more or less experienced what having a party had to offer already. I needed a new challenge, and soloing was the next natural step.
Soloing may seen daunting at first, but if you have played the game before, you have the advantage of foreknowledge. You know what is going to happen, so you know what to prepare. It is actually a test of your skill and knowledge of the game, especially when you solo on Insane Difficulty.
