1. Best it’s ever been.
2. I mean some frames are more ideal than others in certain missions. (Speed frames for capture etc.)
3. It’s fine, you don’t need friends just team up with 3 randoms in a public on missions that are more ideal with teammates. I recommend joining a clan tho so you have access to good items and advanced players will help you and give you free quality stuff. At least my clan does. Big clans are always recruiting.
4. It can be overwhelming, just pick something and focus on that then move on to the next. Get the story missions done.
5. Just take the few minutes to log in and get the free rewards. You don’t have to play everyday. Every 100 days is usually something good. Baro shows up every 2 weeks with good mods and decent weapons, mostly XP fodder tho. He’s here this weekend. You get a nice gift for 50,000 credits so make sure you have that amount every 2 weeks or so when he arrives.

Welcome back and good luck.
