Thedefeatedsearch wrote Oobleck (The most useful source of information in the main show for Grimm) himself states that Grimm grow more powerful as they grow older, and that not all Grimm are still mindless.

Animals act based on 3 things:

1-Instincts.

2-Sense of Survival.

3-Experience.

Grimm are exactly the same. They act exactly the same for the same reasons. Young Grimm however, being ignorants, they think that they can actually win any fight and as such have no sense of self-preservation, leading to berzerks and many stupid deaths.

Older Grimm learn from experience that not every fight is a guaranteed victory, and actively starting them will only lead to death. As such, they choose their fights. They don't rush towards everyone they see, they only do that if it's actually worth it. Many animals do the same.

As for the more powerful part, remember this: Power does not mean just being smarter, or stronger. It means being better. If you and someone else both had the exact level of education, and both grabbed a suit of armor, but you know how to use a sword and the other one doesn't, you would be more powerful by comparison.

Grimm grow armor, strong armor, which already makes them more powerful than Grimm that haven't grown that armor. But that doesn't mean they gain inteligence, because they don't. Said armor doesn't matter shit if they didn't learn anything.

Look at the Deathstalker. It only lasted as much as it did because of it's armor. But it's tactics were identical to younger Grimm; rushing like crazy. Why? Because it never learned anything useful for being in that cave for so long. It's inteligence was the same as the Beowulves from the Red Trailer, it learned nothing so it wasn't more experienced either. It simply had more armor. That's enough to be more powerful than them.
