Mid lane is the best lane to roam all over the map. These champions, such as Talon, Pantheon and Taliyah, make roaming and good macro even easier!
The best waveclear mid laners, such as Malzahar and Xerath, establish lane prio easily, freeing them up to take objectives with their SoloQ jungler!
Mages such as Syndra, Vex and Zoe, are the best burst mages in LoL, as they easily delete an enemy in one skill rotation, with their high single-target burst!
