NO NO NO NO NO.
There is strategic zoom! wtf it's like a billion times better than a minimap!"
Why can't there be both? In my opinion, the strategic zoom is useless, and just cosmetic. Others like yourself might think it's essential to the game
The minimap is infinitely useful- good for spotting a hero quick, getting an overview of a lane, and even specifically like clicking on the minimap where a building is to use a teleport scroll on it (as opposed to manually scrolling over to the building then clicking on it).
