Is ret hate justified?

you ask what weaknesses they have

bubble gets md’d immediately in almost every game since priest representation is also very high, warrior can also shattering throw if there is one in the ss

there’s also usually a mage/hunter/sham in every game - bop/freedom can be stolen by the mage, sham has purge, and hunters will root pallys to infinity while kiting around and burning freedoms/steed on cd

hammer is a magic stun, self explanatory

the only thing that’s truly an unbreakable immunity is spellward but that only blocks casters

searing glare can be interrupted by anyone with a macro, silencing the paladin on ALL abilities for the duration

loh could be considered uncounterable but if a pally needs to resort to lay on hands it’s usually too late and they’re getting blown up anyways

most people who play against blessing of sac at <2000 will continue focusing the sac target versus focusing the ret and cleaving

these are all legit weaknesses that paladin has, with movement still being the number 1 unaddressed issue since the rework which just gave them more ranged damage for who knows what reason - paladins are still extremely kitable by locks, hunters, mage, rogue, etc
