I also forgot with the warlock scorching ray+hex and the class multiclasses well with a variety of martial classes and the sorcerer class and cantrips scale independent of caster classes.
Scorching Ray+hex
Sorcerers can cast hex a lot more
Action surge+ scorching ray/eldritch blast+hex=lolz
Sorcerer Twin Spell metamagic+eldritch blast+hex
Warlocks can also get 2 attacks per round at level 5 so you are really trying to maximise hex+multiple attacks and some spells like EB and Scorching ray enable multiple attacks even if you give up multiple attacks via class abilities due to multiclassing.
Hypthetical lvl 20 Build
Eldritch Knight 6/Warlock2/Sorcerer12 but unlike most MC builds you won't suck at low levels if you take warlock levels early.
