I know we can't really see what, or what number of, aa's people have (although if they get an aa level ach and have that turned on to display, one might be able to see number I guess) so perhaps the requirement should be more along the lines of 'have all necessary class specific aas' for raiding, rather than specify a particular number of aas. If the person can't do a particular thing that is enhanced by or defined by an important aa that may be easier to discern during their recruit period.
I am not taking the freebie auto-grant (I have only 4500 aas earned) so if you up the number required alone, I again won't qualify for months to come yet - and most of the ones I will earn from now on are probably the lowest ones. I can't hold my own against a grey in North Ro (no offensive aas really) but I CAN raid very well since I have all the healing/curing ones, etc.. I doubt I am the only person in all of Norrath who just doesn't want the auto-grant right now.
