Artist of War: Help with Phoenix squad mods, especially speed

I've got Zeb's potency up to over 76%, and in 20+ attempts so far today, I haven't been able to land his daze more than once per match (nevermind the stun). This is both him using his basic as well as being called to assist by both Ezra and Hera.

I know it's just RNG, but I feel like there's a witch or a voodoo practitioner somewhere that I should probably be apologising to.
