Special Game Mode Idea @Riot

So doombots gave me the idea. How terrifyingly awesome and op would if there was a Bossmode game mode, where dragons, rift herald and eventually baron just roam the map attacking anything, maybe make it start off as a regular match for the first 5 or 10 mins, then all of a sudden a dragon flies into your lane and kills you and the enemy, suddenly its not just about winning, you also have to survive through recurring dragon attacks. Dragon/The Boss, gets stronger the more kills it gets and or the longer the game goes.

Thought of this earlier, thought it would be pretty fun, but in a f#ck me theres a dragon/dragons roaming the map kind of way. Edit1: Or make the dragons and other bosses an Extension to Doombots (@Sarutobi)
