what tenhou said was basically why I said to get saki:

I might as well point out that with the current shitty silver drop rates nutaku has atm and the slow pace of events, you'd get extra DCs to buy both spica and saki instead of AW'ing every core unit you are able to. with events as slow as it is, you're better off getting a ranged melee to cover more grounds and letting yourself be better prepared for future events. especially when AW units are NOT a necessity to clearing most of the events, simply making them easier.
