All classes can use scrolls.
Great Weapons Master is missing the choice to use the -5/+10 option; instead, it is always applied.
Dip should not exist, except for poison, and that's debatable. I can't find the exact rule, but application of poison is usually non-combat.
Too few short rests. In 5e, short rests are 1 hour, so you might have 3-4 in a day and could reasonably have up to 6. This completely changes the balance of power for the warlock.
Too much control over familiar actions - in 5e directing them is a bonus action.
Arcane Tricksters do not get Mage Hand for free and it cannot do the abilities it is supposed to have for them, e.g., lockpicking.
Several problems with how on-hit additional damage is applied, e.g., Hail of Thorns, but I don't run the various classes enough to detail them.
