BluEzreal - Questions, Comments, and Ideas

So everyone knows the BluEzreal build on Ezreal;

*Lost but not forgotten

So in this new jungle and new season, I asked "Where can we go with this," and I came up with some ideas

1.) AP BluEzreal Mid:

Now bear with me, I know this sounds odd. But let's break this build down

So what do we have here? Obviously a lot of mana, a shield, CDR, Furor movespeed, 3 SLOWS, and a temporary invincibility to bide time for your cooldowns. This rounds out to a very good AP/Slow based build, the AP equivalent to AD BluEzreal. Notice also how immensely tanky this build is. 110 Armor, and 1,100 HP. All of this on a squish like Ez on top of the mana shield is definitely going to get you out of sticky situations. Like previously mentioned, the Spirit of the Elder Lizard is currently removed, so to replace it's slow we can have Frozen Mallet, however you will most likely need to recover the CDR that it had with Runes and Masteries. This is just an idea, I haven't gotten around to trying it yet, but if you have any questions or if I'm just completely wrong feel free to say something in the comments
