Thanks for the help ^^,. I found that by editing the multiplier you can also change how much movespeed affects the animation rate, which is pretty neat.
In game_character_2 look for this line if @anime_count > 18 - @move_speed * 2
I changed it to if @anime_count > 15 - @move_speed * 2
the lower it is the faster the character will animate (I agree, by defualt it does not animate fast enough to be even close to an original Pokemon game), just adjust it until you find what suits you best :)
Hope I helped.
