With quests it's easy to get OP in driftwood. However, if your not a completionist or story focused, I can see this being a problem.
I wonder how they could address this though. Maybe change your difficulty? I think they need one more difficulty level between explorer and classic. And ideally between tactician and honour. The game is by design meant to be difficult. So classic is going to be quite a challenge.
Have you looked at any mods for the game? I know different mods have addressed or are working on addressing more versatile play styles.
