Dynamic prices resulted in many of the higher end player's salaries getting shot way out of proportion, while no players had any meaningful reduction. Also OL cookies from that period also took a steep increase. This ended about 4 years ago. So if a player's price seem way out of whack, it probably is.
AAA is gone from OLs, but you have an extra 1.6m i think to use for the WW (I am not 100% on the WW part, I don't play OLs)
I can't speak for what the current OL cookies are since I don't play them, but just use general good practices for building teams in whatever format you use (don't draft too many IP/PA, look closely at $/IP and $/PA and look for value).
Nice to have you back, I myself was gone for I think over 10 years before coming back last year.
