I don't understand all these people getting upset about Morde title.

It's really simple

Back before CertainlyT got his hands on Mordekaiser, his abilities (outside of his ultimate) all had metal in them. His Q threw metal shards at enemies near the primary target. His W created a metal storm around himself and an ally. His E threw maces out of the ground to smash anyone in its wake.

I wonder where the idea that he's a metal mage might come from.

and no, these changes weren't for the better
