I could still weep silently into my shirt when I see that even on level 80 my Gerethay is still smaller than the level 9 mob I tamed him from.
To have them grow with each level sure is a nice idea but why shrinking them anyway?
I want a big, filthy lion the size of a truck that I can order to attack people, before I start to put holes in their hide with my big filthy gun.
On level 10 I always expect my cat to go "meow" and then run away. Then my level 10 hunter will take a big gulp, start sweating, put a false smile on his lips and... dies in a very nasty and brutal scene. And on top of it, the tiny lil' cat comes back to lick the dead elfs hand... Pah!
Bigger pets for more fear in my enemies!
