Full strength blasts are a big boost to some units (Most russ variants, doomsday ark, vindicator etc) and Manticores are a parking lot's worst enemy now.
Any word on whether blast weapons can be used on flyers? They can't in apocalypse but I haven't seen confirmation in the new rules. If so they're one of the most reliable ways (excepting skyhammer anti air) to take down a flyer so seems unlikely.
