My friends don't play martial classes, so I do it (a session recap)
I played a Torchbearer 2e one shot tonight, and my GM helpfully provided printed and form filled character sheets for a quick start experience. Yay! We had lots and lots of options to choose from--every Iconic Adventurer from the Dungeoneer's Handbook was there.
Initially I went with a Ranger because that was the only Elf, and I so long to get to be an Elf (the settings I've been playing are weird about them)... But just as the beautiful thing was in my hands, I realized that my friends, the other players, chose a Skald (mean bard) and Burglar (what it says on the box). Oh no! Sounds squishy. We chose a nasty and dangerous haunted tower for our adventure, so this was bad news. I quickly hardened my heart and shuffled my Elf away so I could grab the Warrior charsheet.
That was a great move was kinda pointless, actually, because the one time I could roll on an obstacle to kill something, I scored one success in like 6 dice after using all my Fate to try and send it. Then I made my character fight off the evil Necromancer to die, badly, alone, so my friends could run away and WinTM. Everyone also clapped by the end.
I more or less did this in Burning Wheel with the same GM, but it paid off much better there and the situation was more or less the same--lots of cute Wizards and Arsonists and Thieves, but nobody who could leap through a wall of spewing fire with a minor wound. So I made a basic Betty walking tank that nothing could kill, and it went great. People will start telling you that you hard carried a party if you do this. It feels good and also feels like responsibility... if you're reading this, give the girl who plays a knight in every game a break and put on the armor. For her.
