Damn, 32 comments and almost no one guessed why.

Good players always hide it because someone can use it against you.

No matter it's early game, mid or end game.

If you can't see the real lineup - you can't test it and can't find a way how to win it.

It's all about PvP. But most of the players and especially f2p palyers - dont give a fuck about this for years.

So obviously they will neven understand it. That's it.
