Which I've done WAY too many times... I love the element of surprise and absolutely hate this idea...
By the way - how many pirates (fools) actually attack a Thrall with a rusty cutlass? You shouldn't even be in the thrall room if that's the best you got...
I have found both Thunderspine and World Eater with the thralls - I must be doing something right... I'm guessing the more higher level enemies you attack, the better your odds. But I still LOVE the thrill of finding them!
If I knew what I wanted and where to get it, I would do just that and be done with the game. Everyone would have one of every legendary I'm sure and then fun would be completely gone.
That's why we play Pirates Online... not Farmville
'E' for Effort - but I definitely have to vote 'No' on this idea
