As an alternative you might want to go into the story with someone else, so you don't have to fight alone.
THIS! Adding just one person can make a huge difference. I didn't realize that you can do this until AFTER I was done with my story and got to the last part where it was a dungeon and you had to team up. Then I find out, I could have had help at any point along the way. There was at least a few of them here and there that were tough to solo and I had to do them a few times...so I recommend grabbing a guildmate or a random nice stranger to help out if you find one that you can't solo.
