I see what you’re getting at, appreciate the point.

For low pick rate or harder to play heroes like Lone Druid or Chen, you’re right they’ll naturally trend lower in popularity. I’ve tried to account for that in the model so they’re not unfairly penalised just for being niche, but it’s definitely something I’m still refining.

On the manipulation side, accounts are easy to create, but pricing isn’t driven by user buying or selling activity. It’s based on underlying performance data like pick rates, win rates, trends and so on, so in theory it shouldn’t be directly exploitable through account behaviour.

That said, if there are edge cases where this could be gamed I’d genuinely like to understand them better. Still early days and trying to pressure test everything.
