Okay htis is an easy question to answer
Datamining/leaks indicate we will have 8 party members, A druid, wizard, warlock, ranger, paladin, cleric, fighter, rogue
So the classes I am looking forward to, are Bard, Sorcerer, Barbarian, and Monk.
Whatever class is not a companion will be my canonical class.
If they could spin Volo into a bard companion, that would be great because then I could eliminate that from the list.
(Karlach could in theory be a barbarian, or a paladin, either would fit her whole deal I think)
The more companions the better, so I can pick out my class easier XD
