1 Hit 1 Kill - Blaze Bug In Realms

In Relams Blaze So OP, This bug occurs if the blaze fires a fireball at the player,
If 1 Fire ball hit the player, within any distance, the player will die in 1 shot
even though it's wearing the strongest armor, (Diamond Armor)
Helmet : Protection 4, Thorns 3, Unbreking 3, Mending 1, Respiration 3, Aqua Afinity 1, Mending 1.
Chestplate : Protection 4, Thorns 3, Unbreking 3, Mending 1
Legging : Protection 4, Thorns 3, Unbreking 3, Mending 1
Boots : Frost Walker 2, Protection 4, Unbreking 3, Feather falling 4, Mending 1

In this case, not only do I experience this, all realms members also feel that. Please Fix this bug
