Thief (mostly for RP), Berserker and the Bard. I've only played the latter briefly, but has already successfully supplanted the cleric as a support class for my party.
How is the Thief RP in this game?
I like the option to side with the Zhentarim. When you enter the Zhentarim hideout in Waukeen's Rest, IMO you have a funny encounter with the guard Salazon. The guy is so nervous that you have to calm him down first, before he freaks out. But after that you can just give him a hand signal in rogue language and he lets you through to the hideout. Then you talk to the leader called Zarys. During the first conversation she shows herself directly threatening and the conversation turns out to be more of an interrogation and she is also very perceptive in the process, she even notices when you use the Read Thoughts spell on her and you immediately understand that you shouldn't mess with the Zhentarim. However, if you work for her reliable, you can join the Zhentarim family and get access to their special trading stock. I really hope Larian includes the Faction Agent backgound bcs it fits here perfectly. I expect that with this particular background you will have access to the hideout and extra goods from the very first meeting without doing the Find the Missing Shipment quest for the Zhentarim.
In the first act, you can't experience too much as Thief yet, since it's more tailored to rangers and druids with the Druid Grove. For example, I think it's wasted potential that the Tiefling kids got a boring cave hideout. In a Druid Grove it would make sense to have something like a Robin Hood-like complex with tree house hideouts. But you can find a message in the Harpy's Nest that mentions Ninefingers, probably the Ninefingers of "The Guild" (Name of the Thieves Guild) from Baldur's Gate. Moreover one of the Tiefling kids is dazed by the Harpyies lullaby and you can use this opportunity to pickpocket from that kid, before defending it against the Harpyies. You even can support Mol's little gang of Tiefling pickpockets and then secretly rob their hideout. You can rob vendors and buy the goods you need with their own money and you can do some other minor things, which gives you rogue immersion vibes.
