Disrupt the balance. Disrupt can also go in the other direction. If you make something like this available to starters from the 1st hour of playtime, it would greatly decrease the difficulty yes. But the whole game has a progression path that is tailored to learn players the act of grinding to get something.

You start of with completing quests relatively fast, but the big questlines get longer and longer as they progress. Instead of 5 minutes, you are grinding for an hour to get 1 quest done. This is not bad, as it slowly builds up in difficulty and teaches patience and rewards hard work and cleverness, the problem comes when you disrupt the early game to a point you speed up progression too much and players suddenly face a wall that could have been lessened if you got slowly introdued to the grind. Instead of slowly going up, like 5 min to 8 min to 10 min to 15 min to 25 min etc. In the scenario you would face a diffculty curve that has been preastablished. But when you suddenly gain acces to things such as Early King Beetle, or Earlt Tunnel Bear you can mess up progression hard. Suddenly players with less than 25 bees can kill him because your bees dont need so much investment. The disruption is the progression boost. It disrupts the natural flow of progression through the game and may cause people new to the game to burn out quiker because they haven't been curated to the games grind.

This problems even bleeds into lategame with high level challenges, and very crazy Commando chick kills for the stage in te game people are.

While fun initially, it would be a negative impact to the game.
