I'm not preaching anything... I'm just saying that's the way I use it...
I do use it the way you recommend (finisher or before disengage longer than 2GCDs) but most of the time I forget, and I still don't get punished because of it. The damage increase is just too small for me to notice without a parser.
Let me clarify why I use it to double weave:
1) I have bad ping, so even when I'm single weaving single oGCD, I will still clip through half of my GCD (at 4 GL stacks). I have the same problem with MCH.
2) I can't tell if my finisher (with or without TK) that it will kill the enemy. I'm just... bad
Thanks for the feedback though

I'll try to be better at Monk because I love the job.
