Seeker - While maybe you are trying to keep it close to vanilla (but a bit larger for good reason) change it up a bit. While using right click you have a 50% chance of giving the thing you hit the bleed debuff (the deinon one) with a slight cooldown between each attack. Have the seekers roar shoot a sort of "beam" of energy, it does low damage but when hitting something that gives of charge or has some sort of change buff/debuff it will do 3x or 4x damage (this would mostly make sense as it's a large seeker).

Animal call - When you do any call like fallow all or stop call you hear the invisible rider (the human) instead replace the call and do something like pad did (play as dino), when ever you "call" in that you dino does a sort of emote of one of it's unused animations or even roar which should be done in this mod to!

Possible idea - Have each creatures eyes slightly glow in the dark and the colour would be different for each depending on the species (Eg: wolf = red and saber = Blue). Also when you are low the blood on your body should slightly glow as well a transformed human into a creature hast to be at least a bit magical right?

Transformation - There should be a slight effect of any choice when a person transform like a sudden but slight glow or the human vanishing and the animal forming in and vise versa. Also there should be at least a 10 second cooldown before you can transform back into an animal when you turn back (the time should be able to be changed by admins to)

Anyways great mod and these are just ideas I'd feel would make the mod better.
