In a 150 second interval, a paladin can reliably break 3 fears. 2x bubble + trinket. Game goes longer, you get to break a physical cc, a blind, warrior fear, a stun, scatter, para whatever via bop, you get to break a full silence via aura mastery.
It takes 4 fears to land a full fear on a shaman, 3 on a monk, they can choose to break a stun too.
Druid is the worst but gets compensated by playing spell cleave, leading to a second trinket via mage symbi or ele shaman tremor. They also get a long polymorph immunity through tree form.
Also, any team with a dps shaman breaks your aoe fears. Meanwhile half of the dps classes have a fear break / extra trinket.
Ironically , only healer that eats a full fear is priest considering that it's a statistical improbability to play against a comp without a guy that can purge fear ward. And priest can not break any cc that is already landed without using a trinket as opposed to all other healers. Since this expansion is the instant cc fest, it is more important to be able to break a cc that is already landed but priests have to death blinds, scatters, pom polies, fear ward a warrior fear or a lock howl(which requires fail from their part too). So your getting out of cc depends on doing sick stuff, where as the other healer uses cc break button.
Obviously invis + chastise + fear is overpowered but let's not act like non priest healers don't have the tools to deal with it once it lands. How does priest break other healing classes's unavoidable cc btw? Like a FoJ, bash, ns hex, ns clone, para + monk stun? Coincidentally other healers get to break priest cc.
If I am gonna go oom in first 2 minutes because I have to spam heal while the other healer is rocking %90 mana bar, I would like to have easy time landing my fears (which will be broken by the enemy team's multiple fear/cc breakers numerous times before I land a full one anyway)
Again, I am not saying invis chastise sprint fear is fine and I am not saying holy priests are terrible or anything but please keep in mind that there is also the other side of the story(when it comes to overall cc breaking and cc landing)
