Has anyone noticed that faster you research faster pirates become bigger threat? 25-35 turns into the game I get pirates with 6 ships few turns after that I get pirate fleets with 11+ ships and top tier destroyers.
I'm having pirate troubles as well. Every game I start they destroy me. I feel like I don't have proper time to build a decent armada to fend them off.
Well the pirates advance as you advance, they will always have a little bit stronger fleets than you, so you have to make good use of the perks you have.. and a high lvl commander in your fleet to raise fleet limit. so as your saying using the research option can make things tricky.
I've definitely noticed that the pirates get really fast military upgrades, especially on the harder difficulty settings it gets to be almost impossible to balance economy/expansion/military around turns 50-75. But, getting a commander early I've noticed does really help to stave off pirate attacks really well in the early game.
