This is absolutely not true whatsoever:
In CHEL mode: If you’re playing against silver-level players while you’re at platinum level, the system will make your AI players perform at a silver level to balance things out, and your players will be slowed down.
Can you get me a video of this?
You can spend 2 minutes in the offensive zone, but as soon as the opposing players regain possession, you’re immediately under pressure without having been seriously threatened in your zone.
Please publish it through your console or put it up on YouTube and respond with a link.
EA will never admit it, but all of us long-time players know that’s what’s happening.
Again, it's not happening. This is confirmation bias at play.
