What?

No idea what the latter sentence is about, but there's not much to argue with the former. Plarium probably spent about 30 minutes on the very basic logic they built for combat, and then spent the next five years adding conditional statements to it to deal with all their self-created problems.

Are you can understand able to logic?

What do you mean what? I just activated 13 dark shards and all 13 gave only rare heroes, and the red stones, no matter how much I activated them, gave nothing but rare heroes, do you think this is correct and random works as it should? It’s stupid to do that, don’t you need financial investment in the game? Are you so fed up that you don’t care what the players think about you and your project?

This sentence makes more sense than the initial post.

I think the drop rates are consistent with what's posted about them yes.  No, you don't need to spend any money in the game.  Plenty of players are successful without spending anything.

I don’t know what you’re thinking about, but I’ll tell you this: if the probability of falling out is 5-6 percent, then out of 100 stones, how many red, orange and purple heroes should fall out??? 

Hmm ok, let me try to help.

First of all, it's 0.5% for Ancient Shards to give a "Orange' hero. So technically out of 100, your chance is roughly 50/50

Second, "red" heroes only come from Primal Shards and are extremely unlikely to be pulled from those but cannot be summoned from the "stones" you're referring to.

Lastly, "Purple" heroes are 8% chance so out of 100 you should get between 4-12, depending on RNG Luck
