Those might be interesting, but…
They would require a ton of fine-tuning. We have five characters and four players. They would have to specify at least four different careers, from four different characters. If chosen randomly, it might end up having some strange compositions, and (if limited to four careers) take away the original primary reason for including five characters: Choice. For weapons, there are similar considerations. While most stuff is at least usable, I’d still hate having to play Ironbreaker with 1-H Axe and Handgun. Not to speak about when you’re missing a particular weapon (except the Blacksmith version) and crafting mats to make it. So either every combination would have to be hand-crafted, or there would have to be a lot of conditions set for the possible outcomes. Maube both. Either one is a huge amount of work.
Also, the people who are set upon their favourite setups and/or the metagame won’t leave them for a Deed.
Don’t take me wrong, I do think that more needs to be done with Deeds (starting with giving them out a bit more), and things that give incentive for experimentation and breaking the metagame are certainly good. This one just might be too much work (for the devs) to be worth it.
