Something I've noticed a lot, especially in URF.

Champions with delays on their abilities suffer HARD. People who can execute things instantly always are able to dodge them, because these abilities have a lot of power but are gated by delays. So many champions now have instantaneous abilities, whereas no champions are now made with significant delays on their abilities. Just increase speed of activation and lower the damage on these champions, Riot, because I can feel it now more than ever. It used to not be a huge deal, but now there are so many dodges and things, that it feels almost impossible to play as someone with delays without having someone who can lock down a champion for several seconds(Morgana/Lux).
