Calling 100% F2P players with 4M plus GP and in top arena ranks

@JDIII that's exactly what i wanted to know... I am interesting in knowing how high F2P can go. If there are others F2P that can be role model makes sense in playing game, else I quit.
I know 4M is doable, and I know i ave done that without spending a penny.. had i not taken it slow for few half a year may be 5M.
