Time Piece Farming VS Leeching

No you don't. It's horrible. Leeching > PoT farming. For anyone. PoT are way too rare and hard to get.

I found 16 PoT at O2 with one 4 hour 2x drop card. That's pretty darn good if yeh ask me. Plus, its not like PoT is the ONLY thing you find at TT. with double drop, you're bound to get some equipments and scrolls, too.
