My guess is, if anything, they'll either remove the ability for people to Burst on GP at all, or they'll make so it's actually Burstable. Right now it's a bit wonky the way it works (you can Burst on the second hit but it doesn't hit Tager)
Apart from that I can't see anything they would immediately think needs changing on Tager. They might decide that air loops are dumb and remove them but he has other combo options that are plenty good enough.
