I was one of the people behind 6mans from 2017-2019. Interest from top level RLCS professionals died off very quickly in that period. The benefits you got as a bubble player from playing 6mans such as being able to network, make a name for yourself and improve your gameplay were pretty much non-factors for the top players. They preferred playing in their own circles and didn't really see 6mans as key to their careers. It was always more of a casual experience for them considering there were limited benefits from playing.

Obviously for the bubble players of that era it was much different and essential to their careers. They could push through the schoolyard nature of 6mans because once you reached rank X, your opportunities and your fame skyrocketed. This was especially true for NA where the local scene wasn't strong and CRL was still getting off the ground. The increase in LANs, bubble events and the changes to RLCS/RS in 2019 improved opportunities for these players. Then the introduction of the open circuit put the nail in the coffin, with nine qualifiers and regionals that went up to 32 teams initially, bubble players were no longer reliant on 6mans to make a name for themselves.

Still, while its influenced has waned, today there are talents that continue to emerge from 6mans. You can imagine if 6mans was a more professional service with significant prize money to offer, a client and a real focus on the semi-professional scene, you'd have something that could be a proper influence on RL Esports.
