It was announced 5 days ago. It was directly related to community feedback, and also due to the benchmark tests that Eleon did that proved that the over limit weapons were severely hurting performance.
" * I will revert my “test” of custom weapon limits . With the last season I implemented overlimit weapons than vanilla (6 instead of 4 Rocket Launcher for example) . With your feedback and feedback from benchmarks with Eleon, this wasn’t my best decision.
- However, I will make this for an exchange of damage. A big damage boost should make the revert more fun."
