• Half elf Order of the Ancients paladin
• Shadowheart light domain cleric
• Karlach beast ranger
• Wyll champion fighter

I wanted Karlach in the party, but I didn't feel like I had room for her at the time as a barbarian. Booted Astarion and made Karlach a ranger so that I could still have rogue-like utility. Rogue or bard didn't make sense for Karlach lore-wise. Made Wyll a fighter because it turned out that I could have another melee fighter, and I simply cannot figure out a way to make warlocks as combat-effective as the other classes. And I don't like the absence of a proper spellbook anyway. But I like his personality. I chose paladin half-elf for the player character because there isn't a good-aligned paladin option otherwise, and half-elves get a +2 charisma racial bonus and fey ancestry.

At this point, I could probably restore Karlach as a barbarian and make Wyll a ranger. I like rangers because of the tactical options provided by pets. Particularly birds, because of how few enemy types are immune or resistant to being blinded. Plus, birds can cover ground quickly by flying, without using up an action. It's effectively a teleport that you can use every round.

Playing without a pure offensive caster seemed crazy at first, but it's going all right on the standard difficulty. Shadowheart's light domain spells fill in a surprising number of gaps -- and they are particularly effective in Act 2, which is where I'm at now.

The nice thing is, if I change my mind, reclassing is pretty inexpensive. Unlike many other games of this type, the price does not scale with the number of times you do it, or with character level, or anything else. It's always 100 gold.
