IDEAS TO SPICE IT UP

I only been playing this game about 6 months now, and love it, even after the 522 update lol. I have a few ideas that Id like to bounce off everyone. FIRST is more of a request actually, because of things happining in game I dont get to look and see where a ping for help came from, is it possible to let the lil blue dot at the center of the ping stay on the mini map for a few seconds longer ? NEXT ,I cant tell you how irratated I get when after i get dead to hear that lady say YOUVE BEEN SLAIN hahahahaa can we get rid of that plz . 3RD ,another request is SKINS, can you possibly add NFL team uniform skins ?....that would be very cool...LAST is cool too i think the idea is a COIN BOX, example, every 3 or 4 min a coin box worth 4 or 5 hundred coins appears in a rendom spot somewhere towards the middle of the field inbetween each teams first turrets and anywhere left to right , not only a big help to any champ but when you have that many champs going for the coin box it would make for some awsome team fighting too ofcourse the intervals and amounts vary to whatever you think best but the general idea to me sounds cool idk, just one guy talking here ty
