So when will heimer get a real update?

So to the few heimerdinger players out there we haven't really gotten anything worthwhile for heimerdinger, considering that his passive is already a little bit lackluster. It's barely noticeable, and though it does make for great sieging it doesn't really tie in with the rest of his kit. As long as the enemy has long range burst, you cant do anything with it anyways. His turret ai is a little weird sometimes, which is also kind of a pain in the ass too. I play a lot of heimerdinger in normals, and tbh he is good... for trolling. I do get kills, do damage, but other control mages like zyra can really do so much more with her plants than heimer can. Lastly, to rioters, i would love for you to make his e stun and ult e better. His e stun is really hard to land in the first place, so making the whole thing stun would make it so much better. I don't want to have to ult e to be able to stun on person whos dodging my normal e in my turrets. To actually make anyone use his ult e though instead of the ult q or w, try making it like a mini rumble ult. Have a slight aoe slow and dot after the grenades land along with the slow and stun so it doesn't do so little damage just for a stun. He could use it for more control over the area, which is what he's all about anyway. His winrate is going down with each patch too, which kind of worries me. I think he needs a bit of a buff to make him more relevant so he doesn't get looked over when picking mages mid lane.
