Paralyzed by choice! Not sure who to Legend Dive: End up doing nothing. Is there no Salvation?

Pray to the G11 Gods on this one.

So like most, I have no idea who to dive. The general idea I see is that the Dual Cast LM's are generally superior. But here's the rub.

With Spirit Mote Usage I'm torn between Yshtola. Raines... and Terra. (I Have all of Ysh's SB's and all of Terras, only have Raines BSB and his SSB's)

Ysh seems like a no brainer, she's my goto healer for everything.... but Raines.. is pretty damn strong and when I run mages, he's generally in there.

Then there's Terra. I mean.. she probably doesn't even NEED the Legend Dives but having all her stuff makes her seem like a good candidate still...

Then there's the Physical side which is even more problematic. Cloud is probably my best Double Cast Candidate (USB, no BSB's) but I never use him. I also have Squalls USB (bleh) and have failed to get his much coveted BSB2.

Do i just sit and see if I get it eventually then dive the crap out of him... or do I move forward with a non dual casting LM for someone else.....

Like Agrias (I have all her stuff, even chased for her OSB cause waifu). She's a regular with my main team alongside another candidate.... PCecil. (USB, BSB, OSB). Objectively I figure her imperil would be better than Cecil's cover but when you are racked with indecision nothing is easy.

That's not even counting plenty of other possible candidate that I could think of...

So. What do? Wait some more? Cave and spend now? By the time Squall's BSB2 comes back would I have enough to get his LM dived? (Seriously banking myth on that)
