I don't worry about it. A flat out bent and creased card would bother me, but just the little dings and scratches from use don't bother me at all. I couldn't even tell you where they are, precisely, just from memory.
Yeah, don't worry about it. The only time I did was when my Druidcraft Ace of Cups got bent completely in half & flopped, making shuffling difficult. (Thank you Rodney, for the replacement.) That deck has a tendency to be vincible. The Victorian Romantic is even worse - ask Griz. I think she's said hers is now like pieces of floppy paper but she still manages to shuffle & use them successfully & accurately. I'd be really scared they'd fall apart in my hands.
The more you use your cards, the more scratches, dings, tears (you can fix those with nail glue so they don't spread), fading, etc. happens. You probably will learn to love each & every wrinkle; they add character to a deck. I think that you only have one blemish right now is what's bothering you. Perhaps like looking in the mirror & finding your first wrinkle.
More will come if you use them. Erm, look up aging your cards. Many TRY to make their cards look more used.
