New Game Mode (wall of text, sorry)

I have thought of a new game mode that would shake up the special queue. It also works because everyone has been talking about Doom Bots.

     The mode would be a Doom Bots boss fight mode. You would queue up with three other people(or just yourself and find others). After choosing your character and loading in you would be spawned into a medium sized circle, get 800 gold and are level 3. You get 30 seconds to buy whatever items you want(with Twisted Treeline items). Then your two other teammates get teleported to somewhere else on the map. Next comes the bot(level 5 Doom Bots btw). First is the easiest bot, Annie. But she doesn't spawn by herself. She spawns with her 10 feast stacked Annie. After defeating her(only her not Tibbers) you and your team level up and get healed(not all the way just a percent of their health). The bots are always the same level as you. Then the bots keep getting harder and harder. But as the bots get harder and harder you get stronger and stronger. The point of the mode is to beat all the bots and finally beat Ziggs. Also if you don't want to die you can tag out and bring in another teammate. While you are gone you slowly regen health. If you want to you can come in and help your teammate(of course with a cooldown).

Do you guys think this is a good idea. Also leave some other ideas and criticism in the comments.
