Let's see....
Three groups, each with a paladin and a rogue. So, three of each, I play one of the paladins.
Two witches.
Two wizards.
Two bards.
Two fighters (I am beginning to see a theme here.)
Two clerics.
One inquisitor (and the trend is broken). Sent to keep an eye on my paladin.
One sorcerer.
In the past there has been two rangers, a druid, and a barbarian.
Not a lot of multiclassing. Each party has either one full healer (cleric) and a secondary healer or two secondaries (witch or bard). Not really counting paladins as healers.
From a previous short campaign - two rangers, one barbarian, one witch, one rogue, one cleric.
The Auld Grump, why does this post sound like a word problem in maths class?
