i started in ugc and i would probably recommend it to people who arent really ready for a full commitment to tf2
i ended up playing 3 seasons of ugc before trying esea, which is too much, but it would have been better than getting shit on in esea and potentially giving up on competitive tf2
there is a huge lack of any passion or desire to improve in iron-silver ugc players, and telling them "play esea" doesnt change their interests
idk im kind of saying the same thing over and over but its the same way you would tell a pubber to try tf2center before committing to a team. as long as you explain the downsides of each play environment to them its fine for them to start off slow
