The summoners' spells in League are not in a bad place, but some could use a little QoL love. This is my attempt at that, as well as tackling the larger issue of making flash less dominant and supporting the vision game. Most changes are small, aimed at making thematic sense (such as removing Heal's move speed buff in favor of giving such a buff to Cleanse). Ideally, I think choosing your spells should be the final step in customizing your champion to play the role you want your way. Thus, a greater selection of choice with more nuanced effects.
