((I'll answer using the NPCs who followed you guys.
Did I have another class in mind when I made grot/Thyra/Thoradin?
Not really. The party needed a healer for the first two and Grot and Thyra were just that. Thoradin is what my actual character was in my 4e game I was a player in, but later I swapped his race before he dropped in and he became a longtooth shifter. I gave him a big ass axe, made him tanky and threw him in.
Would I change to a new class?
I'm probably going to keep off the NPC party members for awhile because I could instead add more people to the game (specifically those who were waiting). If I do it again, I may just throw in another cleric.
What is the weirdest character I ever played?
I'm torn between Olon and my elf berserker. Olon was interesting and broke the game, but my elf hated his own race after his village took tree hugging too seriously and began trying to mate with trees. His reaction to seeing a new player show up in the middle of the dungeon after the evil character claims the guy is trying to kill him, I ask: "do you like trees?" And as a dwarf, he says no, so I let him in. My entire trust system was based on that.
Now Olon was also weird because he's the one character who was evil and actually evil compared to the other guy who acted more chaotic neutral. Given the fact he made stupidly high level gear at earlier levels (my DM allows mark of making to stack with master crafter and I could make items that were almost ten levels higher then me... At discount). He was also tied in with my character before him because he murdered his family, and how he got into the party was because he revealed himself before them as he watched my character fail his life's goal. I also told you guys about one person who lost her shit when she saw I was evil, and this was him. She did not trust me one bit and after time and time again, I managed to get friendly with all of them except her who metagames WAYYY too much. So when i had to do an evil act, she was all "GTFO" and everyone else is like "don't donit again". And because she was the leader, and a horrible person in real life, she convinced everyone to either kill me or exile me...
So I killed her boyfriend
I would have killed her too, but the monk (her boyfriend) is fast and hits like a truck. Sadly for him, I had a +7 to my death saves.
I'm going to ask you guys one question on top of this:
What is one incident that happened where you're re playing and something bizzare happened?
Mine was my party in 5e that I DM uses the gnome barbarian as a weapon a lot to the point I'm tempted to give proficency to the bard who keeps throwing/punting her at enemies... And then the Orc berserker picks her up and uses her as a weapon to almost kill the party rogue))
