The starter pack is a solid value but not a must have. DCs are farmable but retain their value well since you need them to buy Awakening fodder. Spica and Chydis are both good enough that you're unlikely to quickly replace them without splashing some cash, in which case you might as well buy the pack and nab Alicia anyway since her pack is good value unless you only buy SC en masse.
