Shifter - Grappling issues

[Wyatt]

Just a quick note, out of the shifter forms the wyvern form cannot grapple. Its hit box is such that it cannot get close enough to a creature to ever be in grapple range. It seems to be the only of the shifter forms that cannot do this. On a side note, shapechange forms cannot use grapple either. Not sure if that is a limitation of the shapechange spell with the new mechanics though. Probably would have to be added to each form manually like knockdown is since the forms cannot use knockdown either unless they have it specifically listed as an ability of within the form regardless of what feat the character itself has.
