I have won over 25 games without getting a key fragment.
Just because i have gotten 5 fragments, doesnt mean i shouldnt get a single other one for AN ENTIRE MONTH. This exponentially decreasing drop chance is just absurd. The fact i am on a 18 win streak and in the entire course of it i havent gotten a single drop is just insane. I was so hyped for hextech crafting, but the this drop rate gating is so frustrating i find it hard to care about the system when i have 3 chests in my inventory i cant even open..
For the record, yes, i play solo. But just because i prefer playing this game alone does not make it reasonable for me to not get a single fragment for over 3 weeks simply because i enjoy playing alone.
Edit1: For the hell of it, I am going to keep this thread updated with how many wins i have gone without getting a fragment. Wins without key fragment: 26.
