OP, to answer your question, yes you can use macros for a BRD. Use the ones posted earlier in the thread that assigned bloodletter and miserys end to heavy, straight, venomous, and wind. I have tested it multiple times on dummies manual and with macros and I literally see no difference aside from RNG. I've also cleared BC using these macros and the only time I have ever had any issue with a macro was getting animation locked and missing a silence like 1 time on turn 2. I also have all my hot keys on my naga set to repeat at their max speed while being pressed so I don't see how a "delay" would even be a problem.
