I have really mixed feelings on fast step recast for non main dancer, that's just broken in the hands of thf main for dyna. Most camps barely support 1 person already.
This is pretty game changing and potentially bad for dynamis when you have crowding since monster respawn will not keep up with staggering from a 3x speed increase in step frequency.
This would be a great time to reconsider the dynamis stagger rate for weaponskills and magic procs if only to alleviate congestion for JA staggered dynamis monsters with these sort of step changes.
THF already get a free pass to D/VD battlefields because of TH and if they can get away with /dnc instead of /nin, they bring super fast step building to the table now even if it caps lower.
My bound to be unpopular opinion on the step recast changes is that these are kept to be dancer main only.
