If New mystery was on here, it should be above Shadow Dragon, maybe even above engage imho. The sniper class was given a very high speed cap which is pretty imperative in lunatic/lunatic reverse. Caeda and Catria will actually do super well in this class since they are usually the first units to hit the speed cap. on top of that, the class is given more physical bulk than the other speedy classes. (swordmaster, berserker, falcon knight etc.) sniper is def a good choice when you need a class that can reliably survive dragons w/o being doubled at all. with enough bulk, they can take 3 hits from most.
