I don't know, Tsubaki got her awesome dragon killer ult as a result of one of these. I could see Ryune getting similar treatment. Also since it was YamaP's pick (twice in fact) he may already have some idea of what he wanted to do.
He picked her twice? Ooooh, optimism rising...
Well, here's to hoping that they don't buff her then have JP players whine about it until they go with something worse. I mean, apparently that kind of thing happens, or so I've heard...
That was because Gremory's original "buff" made her too strong to hit under Sopdet's damage absorb in Arena, genuinely reducing her usefulness. Therefore, it was viewed as a nerf, not a buff.
