One thing that I feel has been overlooked is the fact that everyone only puts one point inti abduction and tongue grab. Seriously, there is no reason to use more than one point in it rather than another ability.
I would like it so every time you leveled it up you get better stat changes than just range and damage. Maybe making the area where you catch your target bigger per level, or make the ability move faster (specifically abduction).
We already are seeing changes to how some of Goliaths abilities and Krakens banshee mines are leveling up, so I wouldnt doubt the other monsters are coming next.
