R isn't U :p They should have made that more clear :p
(Then again one of the things I like about this game is that they leave so much to think about ^^ )
I don't think Rinoa gets herself in trouble a lot. Only once I recall.
I was pretty content with character devellopment by the way. Side quests revealed a *lot* about them all. And showed a lot of history of the world they lived in as well. Like the whole Hyne bit, a lot of people missed that. Then again others didn't and wrote great fanfics based on that information. :)
(SPOILER)(For those interested; the most lengthy part of information about Hyne can be found on the White SeeD ship ;) )
Oh and as a side note, Mercen-X's post covers Squalls feelings perfectly imho ^^
