Oh? I thought that as soon as you captured it you had the option of putting it in your party before battling N. Couldn't you at least check it's nature and stats on the in battle stats screen (when switching your mon)?
Yeah, that's what I meant by exception. Still, I think with a bit of testing we can figure out what actions advance frames. After that it shouldn't be that hard. As soon as I get that far I'm gonna find a stationary legendary with no NPCs around, shut off my CGear and start testing random stuff to see what advances what and see if there's anything new. I think with just a bit of trial and error and luck we'll be able to start causing in one fashion or the other very soon.
I've got that thread on my subscription list. ;) Totally agree. Even now, though we still can't pick our seed, we can use this info to our advantage. When we're SRing if we note the date/time and happen to get good IVs we can turn back the DS to get those same good IVs on most any other mon (with exceptions).
