What is the cost of Ez's amulet now?

I always liked the idea of Ezreal being willing to pay the price for what he wanted. It kept him from being unbearably perfect. Want to quit school, explore the world, and discover the undiscovered? You'll have to give up your magic. Want to get your magic back without having to lose the life you love? You'll have to commit to random interruptions. In the old lore, Ez decided both times that the cost was worth the gain. But in the update, there's no longer a penalty for his amulet, so it feels like he got the best of both worlds. Granted, he finds he now has an "embarrassing" reputation as a mage hero, but what's that compared to being yanked into combat right in the middle of deciphering some ancient Freljordian inscription? (Especially when it's me summoning him?)

The amulet is from Shurima -- could he be in Shurima's debt now? Does the amulet come with some obligation? Some role? Is there a prophecy about it that he's fated to fulfill? And did he know about the potential cost when he took it? (Did he take it? Did it take him?)

I know his new lore is just a sketch. I like that it's short, because it just screams work-in-progress; more to come; stay tuned. What I is hope that when the Riot lore team do update his lore, they won't drop the "count the cost" aspect, because to me that's the most compelling aspect of Ezreal's character.
