This is a good move, and a step in the right direction. Although it will slow down the tankers, I don't believe it will stop them. There is still the problem of a 1% team at the draw, to take the heat off the other 5 members. And the possibly of using the transfer market as pseudo-loans. This just removes the ability to high-exploit the draw with a bunch of 140%+ players coming from a tanker/coiner (usually a tanker).
Paiva's comment would help alot, placing restrictions on leaving and rejoining associations.
Also, maybe having the association draw engine drop the quality of a team or two for the purpose of creating a fair draw. An association can still consist of 6 teams, but the calculation for the draw will not read the quality of all 6 teams, to minimize the impact of exploiters
(180*4 + 1*2)/6 = 722/6 = 120.3% average quality for a 6 team group
(180*4)+1*1)5 = 721/5 = 140.2% average if quality of 6 seed not read if 1% team is 6 seed.
(180*4)+1*0/4 = 720/4 = 180% if only quality of best 4 is read.
This would force the exploiters into tournament with 8* and 9* rivals, due to eliminating the impact of the low quality teams that are exploiting.
Also of the people that like this decision, how reliant is your association upon loans? Of the people that don't like it, how reliant is your association upon loans? Does this decision either positively or negatively impact your association?
