well, not exactly - i just feel like subs happen more - or specifically, periods of time where no subs are allowed, like 4m periods, i just am not seeing them like i used to. so i'm wondering if there is a situation where subs should have been allowed, that got fixed - something along those lines - that would explain some of the difference.
maybe its partially just perspective, i'm looking at this primarily on a low d1 team, where volatility is not a concern (maybe even a friend), as opposed to where i left off and volatility was enemy #1. aberrations and edge cases were important; now they aren't, so maybe its all frame of reference.
however it seems different enough that i am think it could be both... and hoping there was a change somewhere that impacted subs somehow. would like to be able to find that old changelog!
