This is more of the trinity problem.
Power Creep ~ New champions get stronger and do more damage than older ones. (Riot has don't mostly great on this)
Mobility Creep ~ New/Reworked champions just have tons of mobility. (Riot is doing poorly on this)
and finally
Vision Creep ~ More and more vision items/skills/spells/ect... (Rather new issue)
The thing with Vision Creep is how it ties so hard into Mobility Creep. As more and more vision is on the map, players must have champions that can dash over walls and have quick gap closers to AVOID the massive amounts of vision. So Shaco might still have a spot here or there to gank from. Eve is just straight out screwed. But that's Riot for you. If it's on the PBE it's already going to happen so no point in complaining. They really don't care.
