Yah, I have felt a bit guilty with mostly playing the same classes or even the same or similar characters. I gravitate to what I am comfortable with and know well, though I do have may character ideas and builds I brainstorm even if I don't get to play them.
Geoffroy is perhaps my most unique character at the moment, not simply a copy of those I have created in the past and I admit I am left a little uncertain not only roleplaying him but his NPC squire… who happens to be his sister.
If I could, I would be interested in playing a shadow rogue of some sort, perhaps in Dungeons & Dragons 5e using the Rogue specialization Arcane Trickster as the base for the idea.
