if you use only spells for everyone that you do not need to write (more or less) same thing multiple times.I thought they were going to move away from giving monsters spells and instead give them spell-like powers, guess not.
I.E:
Action:
vampire uses Dominate person: at-will.
no need to write anything else, just look at PHB
or fire elemental:
Action:
scorching ray(3rd level): at-will
Fireball: 3/long rest
also, spell-like can be written like in 3E:
spellcasting, but without any spell components.
