The -spd curse continues...

So I got spring Sharena (yay!) but then I checked her IVs out and realized that I have gotten yet another -spd unit (-spd +def the most useless IV for her). So I am stuck with a dilemma, should I just put a spd+3 seal on her or should I give her quick repose and make her a blue tomb (cough, Reinhardt, cough) counter?
