I finally cracked the 100 SS achievement and realized I only have two fully maxed chars. The majority of them are on toons that haven't been dusted off for months, and are unlikely to see the light of day anytime soon. One obvious solution is to stack them/hoard them until you can really find a good home for them, but alas, guys like me spend what we have (just look at my practically non-existent savings account and 401k).
I've stopped losing sleep over it because it is what it is, and I don't see anything changing. Just gotta roll with it I suppose.
