Yeah job itself is not really a broken at all it just that current content shows all its weakness and clunkyness atm. But the thing that baffles me is when even Y-P says that PLD is king of migitation while imo all WAR CD's are better with ALOT shorter recast times(key word here is short)while most of them offer both defence and offence at same time. IB is bacially rampart with potentially having a only 30s CD and on top of that it does damage, RI can be used in magical fights as an offensive CD instead defensive so its not totally wasted unlike Bulwark is, same goes for venge as its still usefull no matter what kind of damage you take but on physical fights its even better and equilibrium again is either offensive or defensive skill depending what you need at that moment.
But most of all its due their short CD that makes me kinda jelly, their longest CD is 120s(180 if counting Holm)and rest are between 60-90s so to make PLD king of the migitation again their CD's needs recast reductions(even situational CD's like TW has 180s recast >_>)and having a shield is imo not very good argument against recast reductions(you can freely nerf block even more if it means shorter recasts on CD's tbh).
