The duo feats may require another player but it doesn't have to slow you don't too much. I recommend queuing into every duo one by one until you reach tier 4. After that point you'll be doing episode feats so it would be easier to explain them under that section. Once you've ran tier 1 through 4 without using consumables or dying you can get into some of the feats that require more thought. Ask a league mate if they don't make sense or require more help than you're likely to get from a random queue pug. One example of a feat that will require more is the kilowog feat. You will want someone more experienced to help with that.
