There are a number of class features that provide benefits to 'spells'. For example, the Eldritch Knight's attacks can give an enemy disadvantage on saving throws from the EK's spells.
Do cantrips count as spells for the purposes of such features?
Obviously, in previous editions when cantrips were just 0-level spells, they would have. However, in 5e there is a level of differentiation between cantrips and spells.
