nah chamber is still good on certain maps and for certain pros to pop off on (yay for example) because of how his super fast op speed and way his sheriff works can single handedly win ecos if you pop off. Chamber is still really good just niche now and picking him can be a double edge sword. The best thing was nerfing his sentinel abilities because picking chamber now is actually a risk with less sentinel abilities to stop flanks and know when someone is entering a site. Its actually a great idea because there wasn't much they could have done to chamber gun without ppl complaining how it becomes useless. Before chamber was just overpower as both a sentinel good for stopping flanks/info , anchoring sites with his teleports, and a semi duelist with his sheriff and operator ult. Now he's a risky sentinel that excels at anchoring sites/angles but lack the info for flanks that cypher and killjoy excels at better on.
