Avast Ye, Admiral!

took like 3 hours, a lot less than i thought it might take, but now hated by all goblins factions now, grinding back to proper reputation level without dropping bloodsail rep is another story, which may take days to weeks to months

some rough calculation:
2.5 rep per mob, requie 31290 kills to get to max level
fastest kill rate without comptition would be about 15 per min optimistically

31290 / 20  = 2086 mins
1564.5 / 60 = 34.76 hrs

ok 34.76+ hours of grindings to go, probabily not that bad if i'm spending about 2 hours / day on this
