Mouse Sensitivity and Game Feels Like it's Underwater

First of all, the mouse sensitivity options are awful. There needs to be way more stages for choosing a sensitivity, as the difference between 0.0 and 0.1 are staggering. Even when you select a halfway decent sensitivity, the camera movement and aiming still feel weird.

On that note, the game just feels... sluggish. I remember PvZGW2 feeling smooth and fluid, and BfN definitely does not. It's like the game is underwater or the characters are swimming through molasses. It's not fluid or smooth at all.

Lastly, the whole game feels like it's on a half-second delay, and there are constant stutters with animations, causing confusing and often detrimental teleports of characters like Snap Dragon and 80's Action Hero (and all the other characters that can teleport) when they use their movement abilities.

I understand it's still 6 weeks till the game "officially" launches, but hopefully these issues can be resolved soon!
