Xyon had been with WWE since 2018, Xia since 2017, so... what?
On a different note, it's always funny to me that pretty much everyone puts it just on the talent's shoulders to improve and "get better", but I never really see anyone questioning if WWE's PC might just not be the best place for training, or rather that it's simply not suitable for every single kind of Wrestler.
And don't get me wrong, of course the talent can only improve, if they work on themselves etc. I just think there are cases where the kind of training a talent gets, might just not be the right one and I wouldn't be surprised if WWE early on put PC prospects into different categories, which have different levels of care etc. put into them.
