Monk new BIS

[Rochetm]

Before 2.1 the BiS for mnk feet section was either allagan or melee, it was pretty much which piece u get first. Allagan free vs myth costing, both stats from the main to secondary. Now 2.1 update allagan boot striking secondary stat crit have been change to determination. So my question now is, why allagan boots still BiS, is there some kind of hidden reflect for wearing multiple allagan piece, is better because it's free or is determination somehow better Than crit?

Det is considered by most to be better than crit. I am going to include SE in my "most" there because they budget it way higher on gear. Notice Det tends to be a much lower value than other stats on gear.
