I honestly think Role Actions are just the most honest part of the homogeneity in jobs, which makes them obvious targets for scrutiny while distracting from the majority of the offenders. Like for example, how much of any tank's "unique" kit is nearly identical to those of other tanks? 1-2-3 combo, 1-2 AoE combo, tank stance, invuln, enmity ranged attack, gap closer, 120 second damage reduction CD, short cooldown damage reduction for party member, short cooldown damage reduction for self. There is so little to every tank that is actually distinct to them and gives them a meaningful personality or play style beyond the VFX. It's a similar situation for healers, too.
