I never liked the idea of multiclassing for my characters. Certain class subclasses are essentially a form of multiclassing, without the risk of spreading yourself too thin. Arcane Trickster, Eldritch Knight, Eldritch Archer, Warlock Pact Boon Pact weapon, certain domain types for the cleric, Bladesingers etc. I always get the idea a jack of all trades is a master at nothing. Mind you certain races excel in these niches and make for great characters and they utilise all their skills to the benefit of the party. I plan on having Gale the evocation Wizard/Wyll with the Fiend Pact for firepower (haven't decided on which yet. Leaning towards Wyll to act as the 'Face' of the party, using that Human everyman to help us out and high Charisma to get us through social interactions), Shadowheart for healing and illusions thanks to her Trickery domain, Astarion as an Arcane Trickster with Enchantment magic, and Lae'zel with her abjuration/evocation magic as an Eldritch Knight. I use the Warlock as a caster, but supplement his low spell slots by having my other party member all know some useful spells to make up the drawback.
