The Stratios is one of my eternal favourites. Weren't it for my eternally empty wallets and it's eternally high price, I'd probably fly around in it a lot.
It looks good, it can warp cloaked and it has decent DPS. The ability to tank more than a couple wet blankets lazily drifting towards you is a nice bonus.
There aren't many ships like the Stratios in EVE. For me, it's mostly either form or function, never both. The Stratios is one of the few ships were good looks and abilities I actually need meet.
Thanks to having a cruise-missile Raven lying around when the Stratios and her little sister, the Astero-frigate, was added to the game, I was able to grind down loyalty points and lay my hands on a Stratios-BPC. That blueprint copy was then transformed into the real deal.
If you want to fly the Stratios, better que up some drone skills. Drones are the main weapon the Stratios has. If you want to use the ship in PVP, you can either try energy-neutralizer or blaster weapons to give you an edge. A PVP-fit isn't even preventing you from doing exploration-content on the side, since you can refit with a mobile depot.
For some reason I could never get into the Astero, by the way. I really tried to love this little frigate, but writing this post made me realize I love cruisers far too much, so that Astero I lost a while ago is probably the last one I'll ever fly. Sad, isn't it?
