So, just hit level 6 on everyone and now (most) of the new classes are really starting to shine. I'm in the creche and killing younlings like Anikin on a bender.
Hexblade - I was digging this with Booming Blade anyways, but now I get astral spirits to aid in the fun. Only killed medium sized people with it so far, but it's always nice to have another free source of damage (as long as the hit).
Shadow sorcerer - (note, I have no idea how to play a sorcerer of any kind well). Still squishy, but at level 6 you get the goodest of good boys in Nimbus, who makes copies of himself when he takes damage. Winning! Haven't managed to pull of the elemental damage trick yet, but I will. Oh, I will.
Giant barbarian - You get to hit a motherfucker with another motherfucker - what more really needs to be said? I am having a bit of an issue with how I want to approach combat with Karlach now. I want to throw shit at you since I now have elemental cleaver and can turn any weapon into Mjolnir, but I also want to hit a motherfucker with another motherfucker and then kick a 3rd... first world problems.
Swashbuckler - Still a work in progress. I'm so used to using my thief as a long-range sniper, and you can do that here, but they play better up close so you can use their dirty tricks.
Swarm keeper Ranger - OH I am LOVING this class. Hit them at range and then do extra damage for free or teleport if they are getting too close (range on the teleport is really small though). Jellyfish are the best choice for swarm, especially if you can get your target in water first.
Arcane archer - Not feeling this one. The trick arrows are nice, but I think you're better off with the ranger for your long-range needs.
Spellsinger - Still working out the kinks here. I think I need to respec Gale to get the most out of this class. Feels odd to have a spellcaster getting into the fray.
Drunken Monk - I really don't know what to make of this class. Having to burn a free action at the start of combat to get drunk is annoying and I don't know how long the effects last out of combat to try and keep him drunk all day. Another class that is pretty squishy for a frontline fighter.
Oath of Crowns Paladin - I'm liking this one so far as a tank. Turn the tides has saved my ass more than once already.
Death domain cleric, Starry form druid, and the glamour bard haven't been tried yet, but I think I might respec Shadowheart into the death cleric. I'll need to wait on trying the druid until I get Halsin or Jaheira.
