And this is why I don't believe in the 0.5s rule for oCDs. If they all had a 0.5s animation lock/delay, why is it I can do PS + IR with no GDC clipping even with higher latency, but struggle to do so with PS + BFB? Skills clearly have their own animation lock/delay.

There isn't really a "Long-term advantage" either (at least, not that I've noticed). Having said that, if I'm not using an X-Pot, I usually put a Legsweep in its place so I can get 1 unbuffed and 1 buffed LS before my BFB runs out.

Ages ago, I used to do my opener so IR would be used before DI, thus allowing your DFD to be buffed by Internal Release as well, but it's kind of hard to fit it all into a perfect sequence without clipping, especially as I'm doing 9GDC BFBs. I'm always tweaking and messing around with my opener. Who knows? It might change again next week! Haha
