i love the war sloop, isnt meant to be armored anyways, but having the same amount of broadsides, and armor as a normal frigate, as well as great speed, doesnt place it as a downgrade in my eyes.
ive sank every ship out there with a warsloop, and probably taken a few hits or none at all, compared to if i tried to use the same tactics with say a war frigate.
its all on how you sail. making the whole "best ship" debate dubious at best.
you might like a war galleon..i think theyre slow and use less. but then again, ive seen my friends use them much more effective than me, and they compliment me on how i can evade being hit in the sloop, so in the right hands, any ship is a good one for their particular style of play.
i have all three, and the only time the wg sees use is mass money making (floating well armored gun platform)
and the frigate is a great all rounder and good for crews/teamwork. but when im serious about sinking/repping as fast as possible, im using the sloop
so whatever i feel is worthless, i can have someone tell me, and usually prove me otherwise

so umm...every ship is good imo.
