With what they are changing your only going to be weaker when you go into a activity under the recommended power level. If your at the required level or above it will progressively get easier. It's to add a sense of power progression to the game which is a good thing. Bullet sponge ads and bosses are a different problem and it revolves around the actual fight mechanics. If the mechanics are too easy then too add a sense of challenge the ads have to become bullet sponges. Rather than knocking the power level scaling thing they are putting in we need to be asking for improved encounters like horde mode where we get swamped by thousands of easy to kill ads or smarter AI's that aren't as strong but offer a challenge in tactics.
