Playing against Jarvan IV

How to counter and exploit weaknesses

1

His EQ can be dodged by side-stepping — the hitbox isn't very wide. Move laterally.

2

J4's R can be dashed over: many champions can simply dash out (Riven, Ezreal, etc.).

3

If J4 uses his EQ offensively, he has no escape for ~12s — punish him when he's in an advanced position.

4

His R also traps his allies: J4 can cage his own team. Take advantage of the chaos if it happens.
