Question about which stars first

[persuasian]

Um so I just started fiesta. I originally planed on tanking but I didn't really think about stats at the time. I just poured all into str. After reading loveless guide I realized I'm adding stats to become a dd. In his or her guide (sorry LOL) it talked about adding spr. Should I of had 25 spr first then str? If so should I stop adding str and add spr to what it should be?

Thanks
