not going to say that rgl should be trying to recruit new players given that they are operating under a volunteer basis. i'm not saying either that they are doing a good or a bad job with current decisions as i'm not well informed enough to make a judgement on that.
though it is very polarizing to see, what i could say, lack of initiative from the highlander community to create their own endeavors or initiatives for trying to lower the barrier of entry into highlander--it seems you guys instead expect rgl to try to do everything on a volunteer basis which is logistically infeasible as it seems they already have enough on their hands trying to run a league with a dying playerbase
not tooting my horn as most of my knowledge is within 6s but considering there is a place called "tf2 coaching central" that has managed to churn out a steady flow of new competitive players into rgl 6s over the course of a few years, it begs the question of how much are people willing to help rgl out given there is a literal ongoing example of a community initiative outside of rgl that has proven successful. of course highlander is a logistical nightmare given it's a 9v9 format, but you can't give and take if all you're really doing is taking.
that being said i tried doing hl production on fireside but there's a lack of volunteers versus 6s when it comes to casting and all that so i've seen only part of the struggle with trying to gather community volunteers from hl lol
