First post here! \o/

So I'm still fairly new to MS, have myself a 68 page. Just a couple questions to start out with:

1. My base dex is at 60 right now, and I've heard dex is pretty much useless post-BB unless I plan on getting equips that require higher dex. Is there a way I can reset the SP I put into dex, and then throw it into str?

2. I've been using slash blast since I got it pretty much, but I've been told that I should've got ground smash a long time ago. Which one is better? As well, I've been told that both will become obsolete once I become a white knight, is this true?

Thanks in advance.
