We are not on DMM. Your not the first to make that mistake. Even though were now finaly on the same patch. Idc about meta. This is a single player game no moba or shooter. You can play it pretty much any way you want and it will work if you figure it out, thats the cute thing about aigis. Guys who call units useless "because of meta" and because there are "more usefull units" dont get it at all. Thats all.
Your answer is flat out no contribution at all as you dont even know or care about what the player asking has as units, needs, wants, prefers or anything, neither care about actualy enlighten him about the units uses, niches, strategies (and those exist for EVERY unit. Even Emilia.). Giving flat out opinions about units being better then her that cant even be compared as they fill a different role. All you wanna do is push down your ignorant belives into other peoples throats not contributing anything usefull.
Sorry to say it that straight forward but its just the plain truth, feel free to feel offended or leave it.
Have a nice day
