Depending on how a sunbreaker wants to run his/her perks they potentially have the weakest armor while in super I can't even begin to count how many times as a voidwalker I've killed a sunbreaker in full super with 2 melee hits. I can't do that to a stormcaller or bladedancer. So with the hungering blade and landfall nerfs I kind of figured that's why they left sunbreaker alone?
