I think its very important that SCs can be killed this way. If they couldn't, then the best and only tactic in the game would be to eventually create SCs. Right now you often can't kill an SC even when you have brought your anti-SC tactics into the battle, since even reasonable protections can be brought by the SC player (like a few Fire or Astral or Death or Water mages for the W9F9 Shadow Vestal assault mentioned above).
