Uber Lab Trials

I've never found all trials before level 90-91 (usually have 10-12 total done but always missing 1).

Hopefully devs will do something to reduce the RNG. The problem is the devs love their RNG. And some of them think it's fine the way it is. Some of them also admitted to having found them all by like level 78 so their extraordinary levels of RNG (like lottery winning odds) makes it so the whole system is fine.

Another option would also be to make certain trials more likely to appear in certain atlas regions or map types. Like Crematorium has a high chance of giving you burning ground, Dungeon maps are more likely to give the spike challange, Orchard gives you Poison Darts etc.
