sry but i just dont get this,
i know im not that great in this game, i had alot of trouble dealing with a hard AI at point blank prior to diplomacy,
so far the 'new' pirates are, well, tough, but overpowered? Hell no! (haven't updated to the patch yet)
Im a turtle by nature so maybe that has something to do with it? recently i just let a planet be swarmed because i was convident my defensive structures combined with the newly created units coming from a border-planet would deal with them, yeah the defensive came in 1 by 1 and there were only a few when the raping began, so i lost the planet a few times (kept sending a colonizer to it to regain it) and the pirates stayed there well over time (the next party had set out to my enemy and my planet was still being attacked)
so yeah, it wasn't as painless as i would have liked it, but i did manage with minimum trouble, this was end-game, meaning my resources where pretty high and the pirates pretty powerfull, as soon as i noticed they would go for me i made trouble to make sure it wouldn't hurt too much and in the end it was a victory where most of the time my attention was somwhere else,
im sure any avarage player could own the hell out of me so if you can't deal with pirates, GET BETTER & STOP WHINING
