It seems because all of kylos requirements have been out for a while now he is just a filler legend until you get the almighty Mary Sue who’s last requirement just became farmable .
With kylo being this bad for a legend I fail to see why he has to negatively impact his team , I bet Rey could wipe kylo and his team out un modded. And before I seen him action I thought of him as a gas 2.0 where you kill his team and then next battle wipe him out but it’s more like gas 0.5.
