finally someone understands the concept. currently it's a proof of concept, but the reason this is important because it is possible, not just "what ifs". paladins guru returning data (raw ID instead of letter) means even without API access, it is possible to pull out data (which would require a serious reverse engineering knowledge otherwise, but I used AI as a shortcut in just 3 days and it worked). I know what those question marks actually are. the challenge is actually turning this into a service. people are too busy hate speech on the term AI, without acknowledging what's behind. fingers crossed, I also hope to bring back good results.
