This. ARR isn't a game with rubbish design like FF11 where you completely replace your ability set as you progress. Bard and Ranger would be basically identical except for BRD's now-and-then songs and Ranger's whatever-abilities. Ranger's abilities wouldn't even have a role, since ARC already has silence, bind, cone AoE, circle AoE, AoE DoT, ST DoT, and off-GCD spam. Additionally, keep in mind that BRD's "utility" is also damage. The only defensive ability in 2.0, RoD, is now purely offensive.
The system was never intended to make interrupts that essential, and it won't be with the changes to debuff resistance. Moreover, if you're choosing two archers in the first place, then ARC is overpowered and needs to be nerfed.
So ARC should have the ideal counterpick to every fight -- just change your job and enter said content, because gear, skills, and stat distribution are all shared?
The only question is whether all classes will get a second job at all. ARR's design abhors redundancy. Ranger as DPS is necessarily nearly identical to Bard. We may not see anything from Archer at all, but if we do, it won't be a DPS.
