OK, so I was playing around with my BTB and mercurial mail, and noticed it made me move faster when lunging.
This would mean that when playing LD, a full flourish combo would be faster.
SO the most annoying possible flourish combo-ing set would be (for LD):
Mercurial set (or demo)
Flourish line/ BTB
2 ASI med trinkets
And a guardian
Thoughts?
