I used to be among the best with battleships a few years ago. Then I took a break from Discovery and the battleship balance changed drastically.
Snub PvP always felt incredibly dull to me. Duels are always the same, and groupfights are always the group chasing one fighter that has to dodge to buy the rest of the group as much time as possible while they shoot the chasers. Get instakilled and you feed regens to the enemy, making it worse for your own team. There is no matchmaking, and some devs prefer to keep the skill gap as high as possible. Plus you always have some groups that will use flimsy justifications to make fights as unfun as possible.
So why bother with things that don't feel fun or have little to no reward when Discovery offers plenty of other content to enjoy without a time investment.
