Spine is incredibly easy once you know what you're doing. The mechanics are implemented in a way that makes it very simple to manipulate them. It's basically this:
- Zone into the encounter
- Kill 3 tentacles
- Get secured and force a roll by standing on his left or right side
- Kill the remaining tentacle
- Kill bloods, get big add to 9 stacks, kill big add at the front of the boss so that it removes the armour plating
- Kill the connective tissue (or whatever it's called)
- Kill all tentacles but one, force a roll.
- Rinse and repeat.
All the while, keep moving from side to side which will reset the roll timer. If you don't already have it get Deadly Boss Mods and don't forget to also download the Cataclysm modules. Make sure you've got sound on too and you will hear a countdown to when he rolls.
Basic rules for a guaranteed kill (even on 25HC):
1. Don't fall off.
2. Don't stop moving except when forcing him to roll.
3. Don't die. I know you're a hunter so speccing into Spirit Bond will keep your healed up.
When I was talking to you on Battle.net the other day I was going to offer to help but I had already done it on all my characters for that reset. However, it's arguably harder with 2 people due to the roll mechanic. You either need to move together or stand on one side each which is easier said than done in practice.
