I know that axe has chance to avoid knock back. But when opponent doesn't have axe on hero but instead they have heart or brand they're not being knocked back. How? I'm talking about pg knock back in arena.
Nowadays the only main reason why heroes can avoid knock effects is because of dodge rate. you will see "miss" when you use your skill or divine.
Although its too soon, now glyphs can too, don´t forget those!
In wheelie <3 we trust
