I thought you were all talking about X-Men Blink so I was very confused 
I think diamonds are for offensive one shot powers while circles are defensive and you cast them on someone a bit like the old glyphs. Static Charge wont do damage but it'll hold an enemy in place and Guardian Spirit wont do anything until the health of person it's been cast on goes below a certain percentage.
I hope crushing prison has made it into a specialisation if it's not a base power, I love that spell it would be a shame to lose it.
Yeah, personally, I'm cool with calling it teleportation. I think the initial lore-bit about no teleporting was mostly to prevent lore issues where people can easily move over vast spaces quickly. Moving within eyesight doesn't make that much of a difference, and doesn't break anything.
I know the justification but the fact is it looked like mages were teleporting all over the place in DA2 Fade Step is just making that available to the player.
