I always try to get as young as possible but due to the scarcity of youngsters these days. They get expensive token wise. And everytime I bid, a number of high level players think it's a ft and start bidding. Transiting to buying older players within the range you mentioned now.
I actually rely heavily on the association tokens to manipulate. If they stopped giving tokens with the change, it might solve the issue for manipulators who lack time. Of course underlying the change, it points toward pay to win which seems to be the direction in the last couple of years. They got us addicted, time for them to milk us for what we are worth.
