SteveCYou can always add team leaders/schedulers yourself on steam and schedule your scrims in advance. Since your team is ranked 46, the likely hood of teams in the lower half of open(25-58) will very likely be around your skill level. Due to the nature of eSports players and their introverted yet competitive mindset most won't go out of their way to add you for scrims since they want to get better rather than sit comfortably in their current ranking.
Of the bottom half of teams in open, only 12 have contact info for scheduling. I had already added the four closest to our team, in addition to some other low open teams lacking contact info I found through IRC.
I'm going to go add some of the other 12 now, the mid open ones.
Thanks for your advice.
