Topic = Blitzcrank: Let's be realistic

I posted this on S@20, but I felt like I should share it here to. It is an Idea I got after reading a question involving blitzcrank. I hope you like

About the steam for blitzcrank. What if Riot were to give him steam instead of mana, creating a whole new ability resource. Although it would seem op since you are probably already thinking "Steam would just regen over and he would never back unless to buy." Now, let's think about this. In my view of steam, I think of water as blitzcrank's resource. As we know, Steam vaporizes into the air, and if you're outside, you can't really get it back. So, if blitzcrank we're to have steam, he would use an ability, and lose some steam. The trick is, THE STEAM DOESN'T REGEN! Blitzcrank instead would have to rely on backing. back to your debate "Then he would back all the time making him a useless lane ally!" AGAIN, LET'S THINK If we were to give blitz a starting source of 700 steam, then he would be able to remain in lane for a decent amount of time, and each level increases his steam by 80 (2140/LV 18). His ability costs would be (Q-100 AL) (W-60/70/80/90/90) (E-0/20/30/40/40) (R-150 AL) Now, Blitzcrank (and any future steam user) would be able to buy special items that can refill steam. This can help blitzcrank be a different type of support without the need of mana, remaining in lane. The last thing to touch about him is the shield passive. It uses available mana to shield him when he is lower than 30% health. Now with steam i'd disagree with him using some of his steam to shield himself. Instead, The passive should shield him based on his MR and Armor

What do you think? Solid or is their a problem?
