Decay Thoughts

I'm a college student now ( an engineering student ) i can't play league all the time and i haven't played for a month now and my lp decayed of course im aware of the system from diamond i dropped to platinum again hmm i think how about extending the period of decay because not all of the players are active not all of the players can play league once a week month or so i loved league of legends i'm playing for almost 4 years now please riot extend the period or decay .. or return the old system back :c
