Take Flight in PvP Question

[Burbankian]

so, I don't really like PvP 

but since it has dailies, I decided to change my skill tree a bit for PvP 

my issue is, when I cast Take Flight

cooldown and damage is shown, but opponents "sometimes" don't go airborne 

is the skill bugged for PvP? 

or does latency have something to do with it? 

tried Raid -> Take Flight, and Dual Strike -> Take Flight  

it just doesn't airborne at times, and I'm not CC'd after casting it, so I don't think it's me getting interrupted  
am I missing something? 

like, do I have to be infront or behind the opponent? 
fought 3x on 1v1, and 3x on tag match today
I only proc'd (airborne) it once on the tag match :/ 

other casts only did the damage

They can F out of your Daze and iframe your F.

Or just tab out and iframe.

Did you skill down the Take Flight path that removes its ability to launch a target airborne?

I also see people doing it twice in a row in PvP.

I do the same as OP, using my five point strike to make them airborne, do my combo, then when they land i stun again with raid, but i cant push them up into the air again like i see alot of other blade dancers doing.

Is there something im missing?
