Every mage does that...why aren't you complaining about
, the difference between them and
is that her strong wave clear is in her ultimate, so her wave clear pre level 6 is actually really bad. Not to mention that the mana cost it takes for her to do what the other wave clear mages does is huge. Vel'koz can Q + W and kill most of the wave if not all of it, for probably around 100-120 mana combined. Ziggs is around the same thing for Q + W but Viktor only needs his E once he gets his upgraded item and thats like 100 mana. If you are saying it takes Anivia 2-3 seconds to clear it (which the other mages I mentioned can do it quicker) that would cost her 75 mana to activate her ult and then 40/50/60 per second. So it'll cost her 155/175/195 mana and that is just 2 seconds and that's why she is forced into double stacking mana items.
As far as utility, they just recently nerfed her there this patch with her wall not granting vision around it which is going to hurt her pretty badly as it is. I'm also kind of tired of people complaining about Anivia's E. If they lowered her E's damage then her damage would basically be really weak and she would not be a threat at all...if they nerfed her E then she would be forced out of mid lane and into the support role, and do you guys really want that?
Also speaking of her E...It's not like she is the only champion to have a strong target spell nuke in their kit. Hell just look at
's Q, that has even less counter play to it and does about as much damage.
Anivia's E: 150 + 50% AP (Empowered to 300 + 100% AP) 90 Mana, 4 second CD requires the use of Q or max duration R and is nothing but damage. Doesn't really synergies with any items and only Thunderlords. Range 650, 1600 speed
Viktor's Q: Both hits: 240 + 100% AD + 90% AP. 65 Mana, 4 Second CD, gains 30% movement speed, and gains a shield based on 8% Max Mana + 15% AP. Requires no other abilities to set up and synergies very well with
+ thunderlords. Range 600, 2000 speed
I'm not trying to say that Viktor is op or anything but just showing that Anivia's E shouldn't be getting as much hate as it is especially when other champions can do as much damage as her E without as much counter play. And don't even say "Viktor has to get close to the target" kind of thing because Anivia's E is barely longer ranged then Viktor so that argument should count for Anivia and Viktor even gets a movement speed boost to get him there.
She doesn't need any more changes, and she was recently nerfed this patch with the Vision of her wall being removed and now all CC stops her ultimate. That is a bigger nerf then you think.
