Long-time lurker here.
I suppose many of us have thought about it at some point (there are a few threads on the forum, although not very successful) creating a build orders calculator and even allowing users to input them into a database where we can upload our most used/preferred builds or have a repository where the community can evaluate the most effective ones, better resolved, etc.
Personally, I started working on a similar idea some time ago (I am the creator of what I called "buildcards") but I believe the ideal would be to have a website with a tool that allows players to calculate all the details they want to add to a build (similar to what LoL build websites do, etc.) and among the entire community, we could have something like a convenient and updated library.
As for me, I am a web/UI/UX designer and work closely with web developers on a daily basis.
If anyone is interested in building at least a rough sketch of this tool and try to improve it with time, feel free to send me a private message, and we can chat on Discord.
Thanks in advance!
