I'm a Solo and not in a clan. I preordered the game but took my time and had recently finished it. In between missions, I levelled through through Portal activities and the Events. I did the campaign on Brave- story and missions were decent. Matterspark is annoying but once done it's not a major concern. After campaign, you can match with other players to replay a random mission. Every hour and a half there's a horde-like activity called The Sieve with some sweet rewards. I got Euonia and I didn't play legendary. There are also some solo activities and Kepler is a place to explore and unlock chests. If you don't get it now then maybe during a sale time.
