i was watching aidan old videos and i noticed the dashing bee attack is there a reason why they dont do it anymore ?

The problem with their original attack and why people didn't like it was that bees are a very effective area denial attack, it could stack and you had no counterplay except leaving that area. And then you had your wave RNG that could overwhelm you with bee husks.

So as a part of a bigger rework beehives stopped sending bee clouds and instead we've received beehive lobbers with the added counterplay of being able to clear the bees by destroying the thrown beehive.
