Here's numbers 51-65. As you can tell from the space between posts on these, it will probably take you a few weeks. The health on these bosses vary from account to account, but just to warn you that on these missions, the health of my bosses was: 10k, 50k, 100k, 150k, 262.5k. The last one took me over an hour to beat so they are tough. Best advice on these is to START the boss fight in Vegas or Italy as it does the most damage. Will do more damage to you, but will be easier to beat the boss in the long run. Good luck with all of them. The improvements in loots are definitely worth it. Enjoy!!
