They wouldn't reset patch, its just the servers. Back to being awful and inadequate. Its EA, they are either bad at managing their infrastructure, their games are poorly optimized or they are trying to minimize server expenses at the cost of gameplay.
Gameplay changes when server capacity is available, until they reduce that capacity in response to the lowered demand. Then its back to slow and unresponsive again. You will notice 20-30min+ periods of wonderful gameplay occasionally, then boom. Back to normal. Its just a shame the games can't be hosted 100% on players PC's during games due to hacking and cheating.
