Once a inhibitor is taken the music could change to a more dramatic one
ore once towers are getting destroyed/a certain number of objectives are taken or gold earned and the MIDGAME comes, there could be a change to music and effect too, same goes for LATEGAME after for example Xmin+
same as howling abyss small but immersive change towards music when the first rig of towers gets taken - which i really liked since it, againe, adds this cinematic epic and rewarding feel to howling abyss, why not also in summoners rift, at least as a toggleable feature? There are a tons of possibilities
