I agree. They should have enough out there so you don't have to wait a day and a half. The minute I get one. The computer gives me the same letter after I no longer need it. It is back wards.
I hear you and that makes it that much more frustrating. I cringe now every time I start a new word and pray for a word with no S's or L's. I always ensure I post 50 Letters a day to help out other players. I just think this really needs to change. It doesn't make it enjoyable at all.
