Daily collection crystals

It is really ridiculous that we have to spent hours hitting veteran modes for crystals! I spent an hour in veteran stone vault and got none?? This is seriously wasting time...why can you guys just raise up the drop rates of the crystal block?? I am sure this daily collection have been annoying everyone! FIX IT PLEASE!

I did 10 vet modes yesterday and got 3 blocks with my main acct. Lvl 21 player. I then was playing my alt account which is lvl 15, did vet modes with it because I haent reached any expert or SS normal. Got 18 blocks! I was so ticked I just had to laugh. My lvl 15 is still on normal frag collections.

+1 I'm stuck on the Simple Block Crystals.
I tried going for runs but I barely got any.

I hope they increase the chances or just make it random so that the next day's quest won't need the same.
