Strategy

Raid: Heroic - 1 MT, 2 OT, 6-7 healers / Normal - 1 MT, 1 OT, 2-3 healers
The fight is a regular tank-and-spank at the beginning. The tank should be careful to tank the boss facing away from the raid and moving him when he cast Scorch. Moving him in a big circle should be the best option.
Also healers should watch for the charged people. They will be places in that pot attached to Ignis belly. Some HoTs should keep them alive.
After a while the boss will start to activate Iron Constructs. OT should tank them away from the raid. You can have more constructs up but you should keep pulling them through Scorch to make them build Heat. When the Heat reach 20 stacks the Construct will become Molten and you should pull him into water to make him Brittle and destroy it. When he dies he will Shatter so is better for some range player to kill it.
If you can snare or root these will ease your way to build up Heat. Just immobilize the construct when he is on Scorch land.
