Mid Lane if for the Casters, Heroes who excel in damage from their abilities. These Heros all have at least one ability that scales over 100%. Casters can be just as squishy as ADC but have the added limitation of watching their mana.
Once you get your starting Items you will head down the center lane. Your goal isn’t so much to take the Tower as Towers take less damage from abilities than basic attacks and as a Caster you are at a disadvantage in that area. When your lane is pushed up, look to left and right lane to help out and Gank. Casters do a lot of damage to enemy heroes and that is where you shine.
With your range, in time fights you will be in the back line with the ADC doing ranged damage. Focus on your Cooldown and mana as without it you are an easy target or worse, worthless in a teamfight.
