Is this a hack or BRD OP issue?

[Isala]

I'm not WHM but I'm pretty sure BRD is far from OP.

I'm both. And BRD is honestly a one-trick pony. It has its burst window, and that is all that it has. There are God knows how many things you can do as a WHM to negate the BRD burst. Virus, Stoneskin, Sacred Prism, Attunement, Tetra, Bene. Swiftcast>Repose> Repose. Or just bloody KITE. If you can keep a BRD from planting their feet for 15 seconds, they cannot kill you. Period. So no, it's not a hack, nor is it a BRDs being OP issue. It's an L2P issue. You'll get better. Just stop using "OMG, BRD2OP" as a crutch.
