We plan to do a nearly complete overhaul for most of the official weapons. My group have took over 40 hours talking and fine tuning along with community response. I would consider the total amount of changes (as in, vanilla and custom-made attributes) that we are aiming to do would rival in size some of TF2's largest official updates. The main idea of this update is to help certain weapons do their job better, plus other weapons to be more fun to use!
Feel free to check out our public spreadsheet to see what we have planned. Mostly to see if you like our ideas.....

If you liked what you saw, please message me about seeing the to-do list spreadsheet (which is a more simple list that separates the vanilla and custom-made attributes). There are currently 165+ attributes/mechanics that need to be made. Even if you don't have the time, anyone who has the knowledge can add notes on the to-do list spreadsheet, so at least someone else would have a better idea how to accomplish what needs to be done.
I do have a limit on what I am aiming to pay for this update all together, so even with that note please message me if you are interested!
EDIT: 08/01/18
Our update is out! I am no longer looking for help.
