While I do not, of course, know what BGEE will do, I would not want to play a BG2-not-EE-style kensai at BG1 levels.
A male half-orc is eligible for the Viconia romance. Only. As a male gnome is eligible for the Aerie romance only.I'll probably go with an Inquisitor, for the sake of recreating Keldorn's awesomeness. I am also tempted to just make a superhuman half-orc barbarian ragemonster, but isn't the half-orc excluded from the romance subplots of BG2?
Don't complain if Kangaxx imprisons your barbarian; all rumors to the contrary aside, the game never claims Barbarian Rage makes you immune to Imprisonment.
