We're yet to get a skill that starts with a Field Spell with that high of a boost on the field. I'd imagine if we got a Neo Space skill, it would probably either be like the HHG skill (and put it on top rather than activate it), or a lost-LP one. It probably wouldn't matter either way, but it would be inconsistent with how they've done it so far.
This wouldn't be consistent with how other similar skills work but it would be nice if you could choose when to activate it so you can play it after using storm neos to clear backrow.
