IceWall now stores 2/3/4/5 charges of TrueIce Shards
Active: Activate to summon a impassable Iceshard for 5 seconds.
Basically think ForceFielding from starcraft 2. This would give players a lot more control and variety in how they want to wall people on Anivia.I think the current casting vector of Icewall is really archaic. Anivia should really have the same level of control over this ability as 
Trap or a Trick1 votesSPEAKING OF RUMBLE, why not just make her W and his ult have the same cast indicator? select a starting point and a destination, so she can more effectively use her wall to block off paths or lead you into a Q
Eternal Torment1 votesagreed, her wall is mostly used to troll people anyway. it is worse than tahm kenches W
Glory971 votesNah, anivia doesn't need more accurate control over her wall. She is already one of the strongest midlaners for soloqueue right now. Her winrate is at 53,7%. Additionally your suggested way of casting this wall makes it even harder for you to completly block of a certain patch in the jungle, because of it taking longer ot cast.
La Bello1 votesto keep a skill purposefully clunky out out of fear of win% is actually a pretty bad reasoning imo.
Glory971 votesits not clunky at all, if you mastered. It's just difficult to learn at first. But if you master it it an insane spell. Froggen the god of anivia uses the wall accuratly to stop the the jungler from dashing at him. Because the tiny knockup can interrupt dashes.
As an anivia player myself I think its more clunky the way you suggested, because it takes so long to cast the wall.
YokoNomi1 votesThere haven't been too many circumstances where committing to the risk of placing a wall ends up working against me as of late. Think Trundle's E, but a bit thinner, in a sense that it has more flexibility and less imposed risk of screwing over your team mates if you know well enough of how it should be used. I see no reason to change it.
