This question was posed to me by a fellow guildmate:
Instead of using the Nishikigoi Pond for city defense, if we use the Sakura Rock a 2nd time in its place, will that give 10% A/D instead of just 5% since there are 2 Sakura Rocks in the set?
Well your Gong would be missing out on the 2 FP bonus but I don't see why the rest of the bonuses wouldn't work.
