I'm still very new so I havn't even fully wrapped my head around what this change means but from my basic understanding here's my take on how it could be positive maybe.
Having only 10 full power upvotes means you have to be really choosy in what you upvote. You can't just recipricate and upvote every comment of someone who upvoted you. Not saying that's good or bad but that's a change.
It also means that the stuff you upvote will be the absolute best content you see which means only the best content will be rewarded
