Suggestions for Anivia
I'm a Anivia main and while I don't generally have problems with the way she is right now, I still feel that it wouldn't be to insane if she had a little help. I know Anivia has always had very high damage but she was balanced around that high damage by all of her weaknesses to make up for it.
Weaknesses like... Lowest Movement speed in the game, With no form of mobility/dashes One of the lowest Defense, and HP in the game Most mana hungry champion in the game Pre-6 she is extremely reliant on the slowest and hardest to land skill shot
Which all of these (and maybe more if you consider them a "weakness" like her Passive at times is underwhelming, and her Wall is useless against most of the current champions being played) generally make it more fair for her damage but honestly when you look at some of the other champions who don't suffer from any of these weakness also have almost the same amount of damage as her it gets a bit annoying.
I feel that the only thing she really needs is 2 small changes to her and she will be in a lot better position. The 2 changes are to her mana cost and her Frostbite (Her E).
As the most mana hungry champion in the game and being able to constantly clear minions easily, it would make sense why her mana cost are a bit high for the late game at least. However, her lane phase ends up suffering a bit to much, especially if she's facing a champion with no mana cost at all and she ends up forced to use skills to keep from getting pushed. With how bad her auto attacks are, I consider her one of the hardest champions to farm with Pre6. Sure once you get level 6, you can farm with your ult if you have the mana to, but getting pushed to your tower pre6 is so hard to really farm with.
With mana cost, the only suggestions I have is for Frostbite (E) and her ultimate (R). For her ultimate, what I normally would think of when using it...is that it's cheaper to use then the average ultimate from anyone else...but using it over time would make it cost more then the average ultimate cost (Average ultimate being 100 mana). But her initial active of her ultimate cost 75 mana + 40/50/60 mana per second, since her ultimate will be out for 1 tick no matter what, you will have to pay the first tick of mana. Meaning that using your ultimate for only 1 second would cost you 115/125/135 mana.
While comparing that to a few other ultimate's with the same style of "toggle" feel... Swain (no initial cost) + 25 mana/second +5/6/7 added per second Maokai (40 initial cost) + 30 mana/second
I feel that her ultimate should get the initial cost reduced a bit, so it won't make it feel like its always more mana then everyone else. Maybe reduce the initial cost to 40 (like Maokai's) that way her lane phase at level 6 won't be so harsh on her mana. Using your ult for 1 second would then only cost 80 mana which again should be how it feels for her...Her ult should cost less then everyones ult and then greatly increase the longer you use it. Another idea for her mana cost would be to sort of give her the same treatment that you gave Annie. I'm not expecting a full refund + CD or anything, but maybe if you kill a target with your E, you should be refunded half it's mana cost (Maybe full mana cost if the target was a champion).
Last suggestion I'd have would be to increase the range of her E. As it is now, landing a max range flash frost (Q) basically means nothing but for the damage from the Q. By the time you get up to your target, the stun and the chill is already gone. Since the range of her Q is 1100, and her E is only 700...if you ended up hitting your target at max range with your Q, you will not be able to follow up on it (Not with her base movement speed). I'd suggest increasing the range of her E to 800? Although 100 is kind of a big jump, so I guess that one would have to be tested a lot.
I know this was a lot of text...so everyone's favorite thing Tldr: While Anivia is some what strong, I feel she could still use some help so here's my suggestions. Lower her Initial Mana cost of her Ultimate to 40 Mana + 40/50/60 mana per second from her current 75 Mana + 40/50/60 mana per second. Allow her to refund half her mana on targets killed by her E (100% Mana refund on champions maybe?) And possibly increase her range of her E to 800 from her current 700.
If you read the tldr and about to downvote/criticize me, at least read the rest of the thread to understand my reasoning for these suggestions.
