Mobility Creep and Damage Creep

All these NEW champions like are impossible to punish because of their mobility! Can we stop mobility creep its ruining this game!

How come these NEW champions like can deal so much damage in 0.5 seconds! Damage creep is ruining this game!

(I know damage creep isn't really a problem solely with one-shotting and is mostly to do with items, but I am tired of people tying these champions/assassins in general to damage creep, especially because many of the champions complained about one-shot you much harder in the past.)
