MASTERY SYSTEM TEIRS

So you know the mastery system, ex; when you get to lvl 4-5 u get that cool banner thing... So recently ive seen ALOT of people saying that they only played 1 champ alot (main) and then had approx (bc i looked on acc) had about maybe around 70k. So what i was suggesting maybe u could make higer ranked banners bc having the lvl 5 banner up until 187k on jax kinda gets boring.. Welp hope rito notices me ;D
