BLM's fine at high ms. Higher delay is mostly a problem for oGCD heavy jobs which BLM doesn't have too many to worry about, nor are they having to worry about double weaves galore.

Bit of bias here, but you could consider SMN!

Apart from general opener considerations, you don't have to double weave that much. There's a lot of windows for single weaves which ping will not impact. I personally main it on NA from EU at 220ms (or 170ish with a VPN). Double weaves are an inevitable clip for me but I just eat and deal with it where I have to, pets can be less responsive but there are tricks you can use to adapt it to your favour. Bahamut windows need a bit more care to ensure 11 real wyrmwaves are performed.

The job can still perform very strongly while being a lot of fun.
