Viola can do chip dmg at fullscreen range, however a decent Ivy wouldn't let viola get that far out, by using Ivy's whip moves, she removes the method of attack - backstep, because no one can move the distance her whip cover after using a move other than her orb; which would be punished or interrupted.
.
ur not supposed to space at disadvantage.... simply put doesnt matter how much space or speed ivy's attacks are or how good the ivy player is, she won't be able to stop a viola spacing out on advantage. also giving the meta at full range, ivy's farthest reaching move is 8b+k which is punishable on block by violas VS 2A+B.
ivy at max range is forced into disadvantage, most ivy players after a few attempts at punishing violas full screen shenanigans will attempt to close the gap.
also keep in mind, as the viola player, those close range 6b+k shenanigans become trash, obsolete. im not saying that a viola with the normal play style can take on an ivy evenly. but tbh if the match up is played differently by the viola player the match up is in either characters favor, maybe a slight advantage towards ivy.
i would say, that Siegfried,astaroth , nightmare and ivy are violas toughest match ups. a viola player with the basic rush in/beat down style of play can easily get over turned by good spacing....
what im saying is for these match ups specifically, throw away the normal viola play style, fight good spacing with better spacing.....
viola can't do anything safely at 5 character spaces..... but siegfried, astaroth, nightmare and ivy can....
siegfried, astaroth, nightmare and ivy cant do anything at 10 character spaces.... but viola can....
see the meta? just because u cant 3b and do combos at 10 character spaces doesnt mean viola does not have excellent tools at full screen.(in fact shes the only character with full screen tools, besides ezio arrow...)
besides ezio, viola is the only other character that can punish full screen.... wether it be a whiff or on block(nothing really achieves that far of a distance anyways)
btw, viola can punish ezio's 6b+k with her VS 2a+b
also its not like viola only has one option at fullscreen... she got a nice set of tools b+k,2b+k, 6b+k, 6bb, 2a+b, 2b+kBE, and VO 6a+b(though this move only covers half screen, its still an i15 move.. a i15 move that covers half screen... most ppl if they are running at you wont be able to react and block that in time "chip")
