Advantages would include gifting credits gained in an unfair way to a main account. One look at just the Hack / Am comps and you can see how very rife it is. Imagine starting at even L tomorrow with what you know now.....Access to those brackets etc , just be easier to stay ahead even with that.
As CC owner I usually will not go below M, but will drop a bit lower only very sometimes. The lower I go the even more looking I do, and often that's several PMs back and forth. I don;t want that to sound grandiose but I do have a duty to keep the club to good people best I can, and also grow it lie that. We have a couple of people who joined as lower tiers who are now a big part of the club, and so I never rule out finding a good person there. In the end I guess I try and impose a sensible civil law type test
I only say that as I don't think relying on WGT will help too much. They do chop a good few first day heroes, but it's beating away flies with a chitty stick. Easy to knock them for it, but I am also not sure what else they can reasonably do either mostly. I say mostly as a few things seem to go that I think they should address, but in the greater scheme doubt huge..
