After playing some games and looking at battle mechanics, there are few details that are not clear to me. This comes down to non-obvious mechanics like accuracy and speed.
Looking at base accuracy of all weapons, they are extra high. From studying some battle logs, it seems misses are extra rare. Meaning, that accuracy bonuses seem to be useless, when base accuracy is already close to 100%.
Speed is another question mark. How does speed affect combat? It is obvious it allows ship to get closer in range, but what after that? Does range affect accuracy? Eg. farther away attack goes, the less accurate it is? Are faster ships harder to hit?
The next complain is size. It seems that right now, building only largest ship possible is the way to go. There doesn't seem to be reason to have fleet of big and small ships. It seems big ships are just as good at fighting small ships as small ones. But small ships, when destroyed are lost forever. If same amount of damage is done to big ship, it can be repaired or at least same ship can participate in next battle until destroyed. It would make sense to make big ships loose accuracy when fighting small ship. This combined with high speed would make it possible to swarm small fleet of big ships with big fleet of small ships. It would also make it necessary to combine various sizes in single fleet, making battles much more dynamic.
