On my solo honour run, which is just starting Act 3, my Tav is a dex Vengeance Pally / Assassin rogue. 23 AC with psychic damage sneak attack smites makes for a great frontline character. Gale is a Wiz 1 / Stormsorc X (his damage potential would be higher as a tempest sorc but Gale has to be a wizard), Karlach is a Thief 3 / Zerker X, and Wyll is a Fiend Lore Bardlock. The only fight that gave me trouble was Grym, because I had terrible luck with his pathing. Every other boss, including W'wargaz, has been a breeze. Locking down enemies with my pally and Wyll, letting Karlach get picks and Gale blow up and debuff enemies has been extremely useful, to the point that it kinda feels like cheating. I'm kinda dreading getting my due against Raphael though, that dude scares me.

I have some MP characters, including a Mephistopheles Ice Draconic Lorebard. Will come online at level 7, so, kinda late. But is already fun. Another one is a Tempest cleric with the Light of Creation glaive and Sentinel. Stay back, blast people with Call Lightning recasts, heal with bonus action, and anyone who gets too close gets pushed back by Light of Creation and the level 6 Tempest feature. Will probably fall off later though, since Light isn't even the best glaive, nevermind weapon for the class.
