Ahoy there @zapalandrox!
Although I can understand the problem you're describing, this game is very much about crew interactions. While parts of the game can be played solo it's just not the way the game is meant to be played. The reward for the content are only rewarded after completing these difficult battles, which either require you to be really good and lucky by yourself, have a very good crew or have the help from several other crews.
Instead of laying down the problem at the developer and asking them to change the game they're making, I'd advice you to look the proper channels to find a crew that can help you do the content. There are more than enough people willing to help either on these forums, the Xbox clubs/LFG, SoT discord or several of the many SoT communities/fleets.
I hope you'll find yourself a merry crew to join you on your adventures. May the winds be in your favour, see you out on the seas!
