Grandmaster Crystal odds for 5 star champions appears to have been greatly reduced

I have opened 148 Grandmaster crystals. In the first 71, I received 4, 5 star champions and 8, 4 star champions. For the next 77 crystals I received 0, 5 star champions and 8, 4 star champions. Is there a bug? Were the odds for 5* greatly reduced in the past month or so? It seems to have definitely changed for 5 star champions. Can anyone confirm this? I might as well not waste any more units on Grandmaster Crystals if this is true. 77 Crystals (15,400 units) down the drain.

You sir need to get your priorities straight. Buying to move ahead in the game is just not worth it!

If people want to spend, it's up to them. It's possible they had Units saved as well.
To the OP, that's a large number of Units. I can understand where you're coming from. However, the results are not uncommon for RNG. 5*s are the rarest drop, and there is no guarantee they will fall. We see the same results with 4*s from PHC. I suspect the drop rates are similar, although there's nothing official to base that on. Just the scale for comparison. Sometimes when we hit a bad patch, it seems something has changed. Recently, I've had the worst luck with Arena Crystals and Units. I don't think anything has changed. It's just peaks and valleys.
