Question About Maokai's VO
This is an issue with the story, just reflected in the game. When Maokai was first introduced, he was a tree from the Twisted Treeline given life through the careless use of magic. Maokai was furious and joined the League so that he could use up the magic that gave him life and "die."
Maokai's has had some tweaks since then, including a complete, visual rework. He is still from the Shadow Isles, but is now an Ent. His new lore makes him appear to have some kind of hope, something to fight and live for. However his VO is still for his old lore, the one where he wanted nothing but to die. Even his appearance is in keeping with his hopeful outlook.
I think it's time he got a VO rework to match his visual one.
