The issue with crusader is the base design. As usual, the class is was built upon a mid term identity instead of committing to an individual thing, as such the design aspect that was supposed to be a strength becomes a weakness as the class lacks (ohh sweet irony) real visible weaknesses.
From what i saw most of the differences between skills are how the damage materialized and, generally speaking, they all do the same on both modes, which is likely to either be left with an almost static cookie cutter skill distribution (or have some weird variations from different scales on each mode). It’s quite unlikely for chant to reach the balance point of fairness and satisfaction as a broad identity class, but knowing IMC they’ll try adding a lot of new gimmicks to try selling out the skills, which will lead to further issues and changes as they can end up overloading the class. For a mechanic like that to work it has to be specialized to the point of niche or offer punctual gimmicks for outer class synergies instead of benefiting itself.
It all goes back to the same core issue, classes lack their individual and unique space to act and become broader for sake of “viability”, in a perpetual loop of direct damage buffs and cycling player insatisfaction as their favorite classes aren’t that good anymore.
