Agree with MattP.
Can we please just try this out and get a bit used to it?
I see it is a big shock for some, but most of your stakes are utterly worthless.
If you don't like being farmed, drop out of UA.
You can also drop lower in UA and be farmed less by people around you because they are less powerful.

Try and cooperate when it comes to gem stakes. Since there is still a bug in place, it will benefit both parties to work together.
