Excess amount of damage from boss than rest of the party even though item level is ok

As stated in title, was raiding with free company friends and during the "Rearing Rampage" mechanic I take an excess amount of damage compared to my other teammates. The healers barely have time to heal me enough to survive. Don't have any vulnerability stacks and majority of the mitigation buffs are placed on me, but I still take way more damage than the rest.

Mages have less health than everyone else and less physical defense, so it is logical that a physical attack would be giving them the most trouble.

Are you using item level 610 high quality food for the vitality? Are tanks, healers and even yourself using mitigation such as reprisal, addle and feint?

Echoing off Jeeqbit,

How do you all manage the mech? My group puts the healers inside on the laha masks so our aoe heals reach everyone, and if properly mitigated and geared we don't even really need to heal the stomps too much besides with oGCDs, (this also carries on comp)
Did any of your gear break or food wear off? Mages have poor Phys Def, so attacks like that hurt us more.
are you close to get hit by the aoe heals? your shield healer should have an ogcd or two to toss your way if needed!
