@Riot: Would you ever consider making an item that lets you build temporary towers?
Just a thought since there's so many new tower-pushing mechanics. Towers seem to die faster than ever, such that pushing a lane can lead to a dead Inhibitor in a mere minute or less, even in early-to-mid game situations.
And seeing as there's some items and mechanics that become useless if there's no turrets left, I think that to improve said item usefulness (i.e. Ohmwrecker), there needs to be an item that lets you build on your team's tower ruins (not on enemy team ruins).
But I also have a sneaking suspicion that Riot will simply say "Never gonna happen". Can I get a confirmation on that, or is the idea of a tower-building item not completely ridiculous?
