Lab Type and Weather
Forum-Index → Suggestions → Lab Type and WeatherMy suggestion is as follows: whatever the weather is the lab has a slightly higher chance of spawning an egg of that type. For example, if it's weather that boosts Steel type Pokemon, any Steel types (as in the type that shows up after waiting 30 seconds for non-premium players) are more likely to show up just a little bit more than others of their same difficulty. Easy ones would only compare to easy ones, and so on, so it's not like a medium would necessarily be more common than an easy egg, if that makes sense.
If this has already been suggested, please tell me, but I think it would be something that helps with the lack of value of almost all bug type Pokemon from the insane amount spawned at the lab.
