So setting aside your own personal opinion on whether the recent BCH surge is a "pump and dump" or the crypto community finally accepting what bitcoin was meant to be all along, what are the drawbacks to larger block sizes which is the central feature of BCH?

The pros are easy enough- faster transactions and lower transaction fees (i currently have a BTC transaction that's been in limbo for the last 24 hours for absentmindedly using a "normal" fee.)

What are the cons of BCHs large blocks? Is it only because it's easier to centralize because the block size is so much larger? Centralization is a legitimate concern in cryptocurrency but is there anything else to consider with 8mb blocks?
