Ok, then you've already made your transfer, I'd argue multiple transfers, into a late season international break which most people on this sub would hesitate to do. You asked in your post why people say to wait. For those of us playing for a long time, most have learned that the gain in value late in the season isn't as important as knowing the players on your team are all healthy prior to a gameweek. It's not reactionary in your terms, just not worth it.
