Ive searched and nothing has been mentioned about this. (apologize if there is)
so here goes.
Pets and their stats grow, but while they grow, do they actually look any different from lvl1 to lvl20?
I would like to see graphical evolutions (differences in how pets look) during each type of evolution (meaning dire, hearty, playful, elder, even new ones would be quite nice) or each level of intervals a pet reaches.
examples:
lvl1-5------ current look and size.
lvl5-10----- slight size change, added looks.
lvl10-15----- ofcourse bigger size, but more updated or "matured" features to the pet.
lvl15-20----- max size, again more features to the pet.
I only suggest these aesthetic/decal features because when I see pets/screenshots of pets from others, the size is the only thing that really differentiates them.
Implementation would not be a cakewalk, since transitions of these features can be done either in real-time (@ the time of pet lvling) or after zoning to give a chance for streaming the effects/features.
So, just a suggestion.
/thx for reading thru.
