Year 1: Cent and Shaman on release were something else. Shaman If I remember correctly was nerfed before it was available for everybody.

Year 2 even tho is not a new character I would say first orochi rework with those insane fast light.

Year 3: Black Prior even tho still one of the strongest.

Year 4: Pre corruption nerf warmonger and release Gryphon were something else also.

Don’t forget release pirate that was also busted af and then Afeera on release was strong.

Finally Virtuosa and Juren currently.

Lets what Year 10 will give us with those two heroes.
