To make the collection of fragments in the BF more fun, I think distribution should be like this, so as not to discriminate the other colors of fragments that nobody wants, and only those who do not know about them collect them. I think it should be like this:
400hp and 150mp silver fragment
400hp and 20defense violet fragment
500hp red fragment
It would be nice to see weapons of all colors, the players would stay more on the server.

Finally there should be the roulette to redeem the fragments and get gifts. that would be an extra

or you mean so you can farm more? you always online for events anyway
