Unity WebGL – Leaderboard problem solve

Hello, my name is Jan and I am looking for Unity developer who can help us with leaderboard. You can check our project here: https://twitter.com/kornhal

Here is how devs are solving leaderboard now:
1) We get top 100 player ids from leaderboard
2) We get player account data(name, fights won/lost, level, rank etc) using player id
3) We get player guild data using player id & show guild icon
4) All of this data is put to UI

But I don’t think this is correct implementation, because it takes around 30 seconds to load/refresh data of another 100 players.
